Abstract

See full text

A semiconductor device includes a data input/output circuit connected to the memory cell array via a sense circuit, and an access control circuit that controls access to the memory cell array. The access control circuit includes: a first signal unit outputting a first signal for activating or inactivating a word line; a second signal unit outputting a second signal for activating or inactivating a bit line and the sense circuit; a third signal unit outputting a third signal for starting or stopping a supply of an overdrive voltage to the sense circuit; and a fourth signal unit outputting a fourth signal for inactivating the word line. The period during which the third signal remains activated is determined in accordance with the magnitude of an external voltage. In the fourth signal unit, the timing to generate the fourth signal is determined independently of the magnitude of the external voltage.
