SEMICONDUCTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To stabilize a read-out operation of a sense amplifier without increasing a chip area largely.

SOLUTION: A switch for controlling the connection of a pair of bit lines and an input/output control circuit is provided at also an input/output control circuit CKT33 connected to only one group of pair of bit lines provided between a Y decoder YD and a memory array MA3. When data is read out from the memory array, data is read out from both sides of the memory array through the input/output control circuit CKT and the switch SWR.
