Abstract
A memory is configured such that two operational modes, including a high-speed access mode in which current dissipation amount is large, but a high-speed access is possible, and a small current mode in which an access speed is lower than that in said high-speed access mode, but the current dissipation amount is small, are provided in the memory. The memory includes a control circuit for executing one of the two operational modes for the memory, in accordance with a mode designation signal sent from the outside of the memory.
