Abstract
PURPOSE:To achieve equi-potential for data bus of an asynchronous static memory in a high speed in a small current consumption, by providing a short circuit with a pair of data bus lines and connecting the bus lines to a low potential power supply for a short time. CONSTITUTION:A pair of bit lines DB and anti-DB' of an asynchronous static memory are provided with a short circuit ST consisting of P type transistors (TRs) P1-P3 connecting both the lines and gate N type TRs N5 and N6 connecting the bit lines to a low potential power supply VSS. The TRs P1-P3 are controlled with a chip selection clock CS1 and the TRS N5 and N6 are controlled with a clock CS2 delayed for a prescribed amount from the clock CS1. Thus, they are connected to the power supply VSS only at a part of period of the standby period and the lines are of equal potential in high speed with a small power consumption. Then, the access at chip selection is made high in speed.
