Abstract:
Embodiments of a memory device are disclosed that may allow for multiple pre-charge voltages. The memory device may include a plurality of data lines, and a plurality of pre-charge circuits. Each of the plurality of data lines may be coupled to a plurality of data storage cells. Each of the plurality of pre-charge circuits may be coupled to a respective data line, and be configured to charge the data line to a first voltage level responsive to a first control signal. Each of the plurality of pre-charge circuits may also be configured to charge the respective data line to a second voltage responsive to a second control signal.
