Semiconductor memory garbage collection

摘要

For semiconductor memory garbage collection, an identification module identifies a garbage collection time window for at least one block of a flash memory array. A garbage collection module garbage collects a first block of the flash memory array with a highest garbage collection level and an open garbage collection time window.

主权项

1. An apparatus comprising:
an identification module that identifies a garbage collection time window for at least one block of a flash memory array and determines a garbage collection level for the at least one block, wherein the garbage collection level is determined from at least one of a free pages number and a partial pages number for each block; a garbage collection module garbage that collects a first block of the flash memory array with a highest garbage collection level and an open garbage collection time window; and wherein at least a portion of the identification module and the garbage collection module comprise one or more of hardware and program code, the program code stored on one or more computer readable storage media.
