  • Patent number: 11082449
    Abstract: Disclosed are systems and methods for diagnosing the health of a plurality of memory cells in a memory array. Diagnostics are initiated from a remote server via an encrypted channel on the memory device embedded in an end-use system. The memory device includes a plurality of memory cells in a memory array. At the remote server, encrypted diagnostics data is received in response to execution of a diagnostics program by the memory device on the plurality of memory cells. The diagnostics data pertains to the health of the memory cells. The encrypted diagnostics data is decrypted into decrypted diagnostics data and the decrypted diagnostics data is analyzed to determine the health of the memory cells. Failure mitigation is performed for the memory device if the analyzing indicates unhealthy memory cells.

  • Patent number: 10331359
    Abstract: Disclosed herein are system, method, and computer program product embodiments for accessing data of a memory. A method embodiment operates by receiving one or more requests for data stored across at least a first memory area and a second memory area of a memory. The method continues with performing, by at least one processor, a wrapped read of data within a first memory area of the memory. The method then performs, by the at least one processor, a continuous read of data within a second memory area of the memory, the second memory area being adjacent to the first memory area. The continuous read starts at a first boundary of the second memory area, and is performed automatically after the wrapped read of data within the first memory area.

  • Patent number: 10120590
    Abstract: Disclosed herein are system, apparatus, methods and/or combinations and sub-combinations thereof, for using a read data strobe signal received at a host device from a peripheral device to convey variable latency (flow) control or report an error in the data content read from the peripheral device. Reception of the read data strobe signal before a predetermined maximum latency time, provides variable latency control back to the host by indicating when valid data is available for capture. If the read data strobe signal is not received before expiration of a predetermined maximum latency time, the peripheral controller is indicating a read data error back to the host.

  • Patent number: 9600384
    Abstract: Disclosed herein are method, system and computer program product embodiments for improving the verification process of a system on chip (SoC). An embodiment operates by employing an active interconnect (AIC) between a processing subsystem (e.g., a central processing unit or CPU) and a plurality of peripherals, wherein the processing subsystem is linked to a plurality of applications via a plurality of drivers, and implementing a common set of software codes by at least one of the applications for a software development process and a hardware verification process. The AIC includes a plurality of communication protocols. During the software development process, the AIC configures at least one of the communication protocols to not enforce a timing limitation on one or more transactions between the processing subsystem and at least one of the peripherals, and a high-level programming language model is used for the peripherals.

  • Patent number: 9477619
    Abstract: Disclosed herein are system, method and/or computer program product embodiments for increasing memory bandwidth when accessing a plurality of memory devices. An embodiment operates by executing, by at least one processor, a first read operation to read data from a first memory device following an access time for the first memory device. The embodiment further includes executing, by the at least one processor, a second read operation to read data from a second memory device following an access time for the second memory device. The access time for the second memory device is substantially the same or longer than the access time for the first memory device plus a time it takes to read data from the first memory device.
