A storage module may include a controller that has hardware path that includes a plurality of hardware modules configured to perform a plurality of processes associated with execution of a host request. The storage module may also include a firmware module having a processor that executes firmware to perform at least some of the plurality of processes performed by the hardware modules. The firmware module performs the processes when the hardware modules are not able to successfully perform them.

Hardware and firmware paths for performing memory read processes

Buffer memory reservation techniques for use with NAND flash memory include dynamically reserving regions of the buffer memory, responsive to a read/write request. Where the read/write request includes a plurality of data transfer requests, following completion of a data transfer request, the reserved buffer space may be recycled for use in a further data transfer request or for other purposes. During fulfillment of a read request, a buffer region is reserved from a larger buffer pool for a time period significantly smaller than the time required to execute a sense operation associated with the read request. The reserved buffer region may be reused for unrelated processes during execution of the sense operation.

Buffer memory reservation techniques for use with a NAND flash memory

A non-volatile memory system that has multiple memory banks initially assigns logical addresses to memory banks according to an assignment scheme, maintains this assignment for a period of time, then identifies frequently-written data ('hot-data') assigned to a memory bank that is heavily worn over that period of time and reassigns it to a less worn memory bank.
