Abstract
A memory control circuit for writing or reading digital data at a high speed without increasing access speed to the memory circuit. The memory control circuit includes a control signal generation circuit for generating a first write enable signal and a first read enable signal of a first memory circuit, an address generation circuit for generating an address signal designating a data write address of the first memory circuit and a second memory circuit, and a write data supply circuit for supplying write data to the first and second memory circuits. A shift circuit is connected between the control signal generation circuit and the second memory circuit to generate a second write enable signal and a second read enable signal by shifting the first write enable signal and the first read enable signal by one cycle of a data write cycle or read cycle. The write data is written alternately to the first and second memory circuits in response to the first and second write enable signals. The data written to the first and second memory circuits is read alternately from the first and second memory circuits in response to the first and second read enable signals.
