Abstract: A system and related method, including system memory with a source memory block and a destination memory block each of a memory block size, a first volatile memory and a second volatile memory, each of a volatile memory size. The system includes processing circuitry to receive a garbage collection request associated with the destination memory block. The processing circuitry then determines whether the memory block size is greater than the volatile memory size and pauses data change operations but allows for passive operations to continue. While data change operations are paused the processing circuitry loads a first portion of data of the source memory block to the first volatile memory and a second portion of the data to the second volatile memory. The processing circuitry writes each portion of data from the volatile memory to the destination memory block to complete garbage collection and unpauses the data change operations.

Abstract: In one example, reads in a NAND memory device are tracked for sub-groups. When the number of reads to a sub-group meets a threshold, the data at the wordline on which the threshold was met is moved along with the data at neighboring wordlines to an SLC block without moving the entire block. The performance impact and write amplification impact of read disturb mitigation can be significantly reduced while maintaining some data continuity.

The L2P indirection table has a plurality of entries, each entry to store a physical block address in the block addressable memory assigned to a logical block address. The solid state drive including solid state drive controller circuitry communicatively coupled to the persistent memory and the block addressable memory. The solid state drive controller circuitry including a volatile memory to store a logical to physical address indirection table cache and circuitry to monitor the logical to physical address indirection table cache and to write dirty logical to physical entries in the logical to physical address indirection table cache to the logical to physical address indirection table in the persistent memory.

Abstract: Dirty Logical-to-Physical (L2P) entries in an L2P indirection table stored in a host volatile memory buffer are flushed to non-volatile memory in the solid state drive through the use of a write-back mode based on flush checkpoints. The use of write-back mode to flush dirty entries in the L2P indirection table to non-volatile memory in the solid state drive based on flush checkpoints results in an increase in the write bandwidth of the solid state drive.

Abstract: Techniques for preventing read disturb in NAND memory devices are described. In one example, reads are tracked for sub-groups. When the number of reads to a sub-group meets a threshold, the data at the wordline on which the threshold was met is moved along with the data at neighboring wordlines to an SLC block without moving the entire block. The performance impact and write amplification impact of read disturb mitigation can be significantly reduced while maintaining some data continuity.

Abstract: A software and hardware architecture framework utilize the specifications of Universal Serial Bus (USB) Type-C and Power Deliver (PD) to provide fine grain throttling of a processor (e.g., system-on-chip (SoC)). Based on an external charger connection or disconnection, a low latency fine grain power budget loss or gain indication to the processor is delivered. The mechanism of various embodiments is also applicable to connection or disconnection of VBUS powered peripheral devices to the system. The net power loss or gain available to the SoC and System is proportionally used to scale the processor throttling.

Abstract: A nonvolatile memory supports a standby state where the memory is ready to receive an access command to execute, and a deep power down state where the memory ignores all access commands. The memory can transition from the standby state to the deep power down state in response to a threshold amount of time in the standby state. Thus, the memory can enter the standby state after a command and then transition to the deep power down state after the threshold time.
