ABSTRACT:
An arrangement is provided for the input level of an output buffer from fluctuating when a memory device goes from an active state to an inactive state. To achieve this, a level holding circuit is provided at a point connecting an output of a sense circuit for amplifying a signal read from a memory array to an input of an output buffer. The level holding circuit is constituted so that, when the sense circuit goes from an active state to an inactive state, the level holding circuit holds an input level of the output buffer at a time immediately before the sense circuit goes inactive.
