Abstract:
An apparatus for reading a bit of a memory array includes a bit cell column, voltage enhancement circuitry, and control circuitry. The voltage enhancement circuitry is configured to couple a bitline to a reference node. The control circuitry is configured to, in response to a read request for a bitcell element of a plurality of bitcell elements, couple a current source to the bitcell column such that a read current from the current source flows from the source line, through the bitcell column and the voltage enhancement circuitry, to the reference node and determine a state for the bitcell element based on a voltage between the source line and the reference node. The voltage enhancement circuitry is configured to generate, when the read current flows through the voltage enhancement circuitry, a voltage at the bitline that is greater than a voltage at the reference node.
