Abstract

A method for operating a non-volatile memory storage system (102) is provided. In this method, a write command is received to write data. The write command is allocated a timeout period to complete an execution of the write command. Within the timeout period, a portion of a garbage collection operation is performed. The data associated with the write command are written to a buffer associated with the non-volatile memory storage system.
