Abstract
In a serial memory which internally converts serial input data into parallel data and writes the data into a memory array two or more bits at a time, and which reads data two or more bits at a time from the memory array and internally converts the read data into serial data for output, circuits are provided that allow selective reversing of the order of parallel conversion on the serial input data and of serial conversion on the parallel data read from the memory array. This serial memory is also provided with a memory controller to reverse the ascending or descending order of the access address for the memory array in the read and write operations.
