Variable-size flash translation layer

摘要

A method for using a variable-size flash translation layer. The method includes reading an entry in a map based on a read logical block address in a read request to obtain both a physical address of a particular page in a memory and information regarding compressed data with a variable size; converting the information to both an address in the particular page and a number of read units in the memory that contain the compressed data; and reading the compressed data from at least the particular page in the memory based on the address and the number of read units.
