Abstract

PURPOSE:To shorten the access time of a memory by utilizing access to alternate prescribed bits 0 and 1 of an address. CONSTITUTION:During access to a memory, a chip enable signal CE and address inputs A0-A3 are supplied, and a clock generator CG12a or 12b is selected according to whether the A0 is 1 or 0, thereby generating various timing signals. For example, while the CG12b is enabled and the CG12a is disabled, a memory matrix 16a is precharged sufficiently, and a memory matrix 16b is also precharged one cycle before, enabling necessary access.
