摘要： A state retention power gated cell includes a logic cell arranged in two or more rows. The logic cell has an active layer including at least a first well and a second well disposed in first and second rows, respectively. In a normal operation mode, the first well is powered with a first bias voltage, the second well is powered with a second bias voltage, the first power supply line is powered with VDDC, and the second power supply line is powered with VDD. In a standby mode, the first well preferably is powered down, the second well is powered with the second bias voltage, the first power supply line is powered with VDDC, and the second power supply line is powered down.

摘要： An electronic device has a power control module for causing selected functional blocks to run in a low power mode of operation, while leaving other functional blocks supplied continuously with power. A power mode control distribution network includes serially connected chains of buffers in a distribution tree for distributing power mode control signals received at a common input end to respective output ends which are connected to respective functional blocks. In the low power mode of operation the power control module causes power to be supplied continuously to output buffers at the output ends of the chains while causing power supplied to other buffers to be reduced or cut-off. The output buffers include feedback paths for causing the states of the output buffers prior to the low power mode of operation to latch during the low power mode of operation.
