摘要: A method for flash memory management comprises providing a head pointer configured to define a first location in a flash memory, and a tail pointer configured to define a second location in a flash memory. The head pointer and tail pointer define a payload data area. Payload data is received from a host, and written to the flash memory in the order it was received. The head pointer and tail pointer are updated such that the payload data area moves in a circular manner within the flash memory.

摘要: Disclosed are techniques for flash memory management, including tracking payload data via one or more data structures configured to define the size of logical pages in a flash memory. In various embodiments, the logical page size may be larger than, equal to, or smaller than a physical page size of a flash memory chip.
