Abstract

An improved flash EEPROM memory-based storage subsystem includes one or more flash memory arrays, each with a duplicity of data registers and a controller circuit. When data are read from a flash array into a data register, the data is copied to a second register so that, during the ensuing program operation into the same array, the data may be transferred to the controller for the purpose of checking the data validity. This creates an improved performance system that doesn't suffer data transfer latency during copy operations but that is able to guarantee the validity of the data involved in such operations.
