Abstract
An integrated circuit device that has improved write margin at low operating voltages is disclosed. The integrated circuit device can include an SRAM array that has end power select circuits that can include selection circuits that provide a controllable impedance path between a power supply potential and an array power line. A power supply detection circuit may provide an assist enable signal when a power supply potential is low enough that write assist is needed. A power control circuit may provide end power control signals to end power select circuits to selectively control an impedance path between a power supply potential and an array power line to provide an I-R drop to a selected memory cell. In this way, write margins may be improved at low operating voltages.
