Abstract
A dual-port memory requiring fewer serial input/output pins. A multiplex/distribution circuit multiplexes data for n rows read from a memory cell array into m (m<n) pieces of serial data and outputs the same to the serial I/O port, and distributes m multiplexed serial signals input from the serial I/O port into n serial signals.
