ABSTRACT:
A method of executing states of a clean-up state machine while executing a command from a host CPU to read a sector of data stored within a memory array. First, a number of sectors of data are copied from the memory array into a sector buffer. Then, while the host CPU is reading sectors from the sector buffer, a number of states of a clean-up state machine are executed to aid in the conversion of invalid user data into free memory. Also described is a solid state memory disk that converts invalid sectors of data to free memory while executing a read command from a host CPU.
