Abstract: Customized root processes for groups of applications in a computing device. A computing device (e.g., a mobile device) can monitor usage of applications. The device can then store data related to the usage of the applications, and group the applications into groups according to the stored data. The device can customize and execute a root process for a group of applications according to usage common to each application in the group. The device can generate patterns of prior executions shared amongst the applications in the group based on the stored data common to each application in the group, and execute the root process of the group according to the patterns. The device can receive a request to start an application from the group from a user of the device, and start the application upon receiving the request and by using the root process of the group of applications.

Abstract: Systems, methods and apparatuses to intelligently migrate content involving borrowed memory are described. For example, after the prediction of a time period during which a network connection between computing devices having borrowed memory degrades, the computing devices can make a migration decision for content of a virtual memory address region, based at least in part on a predicted usage of content, a scheduled operation, a predicted operation, a battery level, etc. The migration decision can be made based on a memory usage history, a battery usage history, a location history, etc. using an artificial neural network; and the content migration can be performed by remapping virtual memory regions in the memory maps of the computing devices.

Abstract: A computer system includes physical memory devices of different types that store randomly-accessible data in memory of the computer system. In one approach, access to memory in an address space is maintained by an operating system of the computer system. A virtual page is associated with a first memory type. A page table entry is generated to map a virtual address of the virtual page to a physical address in a first memory device of the first memory type. The page table entry is used by a memory management unit to store the virtual page at the physical address.

For example, a set of networked computing devices can each be configured to execute an application that accesses memory using a virtual memory address region. Each respective device can map the virtual memory address region to the local memory for a first period of time during which the application is being executed in the respective device, map the virtual memory address region to a local memory of a remote device in the group for a second period of time after starting the application in the respective device and before terminating the application in the respective device, and request the remote device to process data in the virtual memory address region during at least the second period of time.

Abstract: A computer system includes physical memory devices of different types that store randomly-accessible data in a main memory of the computer system. In one approach, an operating system allocates memory from a namespace for use by an application. The namespace is a logical reference to physical memory devices in which physical addresses are defined. The namespace is bound to a memory type. In response to binding the namespace to the memory type, the operating system adjusts a page table to map a logical memory address in the namespace to a memory device of the memory type.

Abstract: A computer system includes physical memory devices of different types that store randomly-accessible data in a main memory of the computer system. In one approach, data is stored in memory at one or more logical addresses allocated to an application by an operating system. The data is physically stored in a first memory device of a first memory type (e.g., NVRAM). The operating system determines an access pattern for the stored data. In response to determining the access pattern, the data is moved from the first memory device to a second memory device of a different memory type (e.g., DRAM).

Abstract: A wear-leveling process for a memory subsystem selects a source chunk to be removed from a usable address space of the memory subsystem to distribute wear across all available chunks in the memory subsystem. The memory subsystem has a plurality of non-volatile memory components. The plurality of non-volatile memory components includes a plurality of chunks including at least one chunk in an unusable address space of the memory subsystem. The wear-leveling process copies valid data of the source chunk to a destination chunk in the unusable address space of the memory subsystem and assigns the destination chunk to a location in the usable address space of the memory subsystem occupied by the source chunk.

Abstract: A computer system stores metadata that is used to identify physical memory devices that store randomly-accessible data for memory of the computer system. In one approach, access to memory in an address space is maintained by an operating system of the computer system. Stored metadata associates a first address range of the address space with a first memory device, and a second address range of the address space with a second memory device. The operating system manages processes running on the computer system by accessing the stored metadata. This management includes allocating memory based on the stored metadata so that data for a first process is stored in the first memory device, and data for a second process is stored in the second memory device.

The apparatus also includes a camera, and a processor in the computing device. The camera can be connected to the computing device and/or the user interface, and the camera can be configured to capture pupil location and/or eye movement of a user. The processor can be configured to: identify a visual focal point of the user relative to the user interface based on the captured pupil location, and/or identify a type of eye movement of the user (such as a saccade) based on the captured eye movement. The processor can also be configured to control parameters of the user interface based at least partially on the identified visual focal point and/or the identified type of eye movement.

Abstract: A computing device (e.g., a mobile device) can execute a root process of an application to an initial point according to patterns of prior executions of the application. The root process can be one of many respective customized root processes of individual applications in the computing device. The device can receive a request to start the application from a user of the device. And, the device can start the application upon receiving the request to start the application and by using the root process of the application. At least one of the executing, receiving, or starting can be performed by an operating system in the device. The device can also fork the root process of the application into multiple processes, and can start upon receiving the request to start the application and by using at least one of the multiple processes according to the request to start the application.

Abstract: A memory sub-system configured to be responsive to a time to live requirement for load commands from a processor. For example, a load command issued by the processor (e.g., SoC) can include, or be associated with, an optional time to live parameter. The parameter requires that the data at the memory address be available within the time specified by the time to live parameter. When the requested data is currently in the lower speed memory (e.g., NAND flash) and not available in the higher speed memory (e.g., DRAM, NVRAM), the memory sub-system can determine that the data cannot be made available with the specified time and optionally skip the operations and return an error response immediately.

Abstract: Exemplary methods, apparatuses, and systems include determining that data in a group of memory cells of a first memory device is to be moved to a spare group of memory cells. The group of memory cells spans a first dimension and a second dimension that is orthogonal to the first dimension and the spare group of memory cells also spans the first dimension and the second dimension. The data is read from the group of memory cells along the first dimension of the group of memory cells. The data is written to the spare group of memory cells along the second dimension of the spare group of memory cells.

Abstract: An example method includes determining a time between writes in place to a particular memory cell, incrementing a disturb count corresponding to a neighboring memory cell by a particular count increment that is based on the time between the writes to the particular memory cell, and determining whether to check a write disturb status of the neighboring memory cell based on the incremented disturb count.
