| Abstract | CIRCUIT POWER.CONTROLLED-10 A semiconductor integrated circuit has an SDRAM and a group of elements, whose power consumption is controlled (referred to as “power-controlled block”). The power-con trolled block includes a CPU and a memory control circuit. A power control circuit outputs a power-down Signal to an output-fixing circuit when a power-Saving mode Setting command is supplied from the CPU. A control signal for commanding Self-refresh operation is generated from the output-fixing circuit to the SDRAM. The power control circuit thereafter Stops the Supply of power to the entire power-controlled block in response to a power control Signal. When a restart Signal is provided, the power control circuit starts the Supply of power to the power-controlled block. A power-Saving mode release command is then generated from the CPU to the power control circuit, and the power-down signal is Stopped. Thereupon, the output-fixing circuit provides a control Signal generated from the memory control circuit directly to the SDRAM. |
