Memory macro with a voltage keeper

摘要

A memory macro includes a first data line, a second data line, a first switch and a voltage keeper. The first switch is configured between the first data line and the second data line. The voltage keeper is electrically coupled to the second data line. The voltage keeper is configured to control a voltage level at the second data line in response to the voltage level at the second data line during the first switch electrically couples the second data line to the first data line.
