ABSTRACT:
A semiconductor memory device includes a plurality of memory blocks, a write circuit for writing data into the memory blocks, a read circuit for reading data from the memory blocks, a plurality of serial registers, each of which is connected to the corresponding memory block to output serially a plurality of data read from the memory block, a plurality of switches, each of which is arranged between two adjacent ones of the serial registers to connect the serial registers in series, and a coincidence detection circuit for detecting a coincidence of data outputted from a final serial register arranged at a final end of the serial registers connected by the switches with data outputted from a serial register arranged immediately before the final serial register.
