    摘要: When an address transition detector (13) detects a transition of an address signal (Add), it produces an address transition detect signal (SATD). The signal (SATD) drives a bit line initializing circuit (6) which in turn initializes paired bit lines (5, 5 ), and ini­tializes the paired output lines (26, 26 ) of a sense amplifier (10). At the same time, a clock signal gener­ator (14) generates a clock signal (φS) for a predeter­mined period of time in accordance with the address transition detect signal (SATD). The clock signal (φS) is supplied to the sense amplifier (10) and a data out­put circuit (11). The sense amplifier (10) is active during a period that the clock signal (φS) from the clock signal generator (14) is in an effective level. The output terminal of the data output circuit (10) is placed in a high impedance state during the period that the clock signal (φS) is in an effective level. During the other periods than the effective level period, the data output circuit (11) produces a signal (Dout) corre­sponding to the data as is read out of a memory cell (7) and outputted by the sense amplifier (10).

    摘要: A memory is presented. The memory includes a plurality of memory cells, a wordline coupled to the plurality of memory cells, a sense amplifier coupled to one of the plurality of memory cells, and a timing circuit configured to enable the sense amplifier. The timing circuit includes a delay stage and a dummy wordline. The dummy wordline is configured to emulate at least one portion of the wordline. An apparatus is presented. The apparatus include a first memory having a first wordline coupled to a first number of memory cells. A second memory having a second wordline coupled to a second number of memory cells. Each of the first memory and the second memory includes a timing circuit to enable a memory operation. The timing circuit includes a delay stage corresponding to loading of a third number of memory cells. The third number is different from the first number.
