Abstract
A memory instance comprises a plurality of banks of storage cells to store data values, and input/output circuitry shared between the plurality of banks for receiving write data or outputting read data. Each bank of storage cells supports a power saving mode and an operational mode. A control interface receives power control signals for controlling use of the power saving mode. Bank power control circuitry individually controls, for each of a plurality of subsets of banks of storage cells within the same memory instance, whether that subset of banks is in the power saving mode based on the power control signals. For at least one setting for the power control signals, one subset of banks is in the power saving mode while another subset of banks in the same memory instance is in the operational mode. Also disclosed is power control circuitry which selects the power mode to use for each subset of banks and generates the power control signals.
