Abstract
A memory array comprises a plurality of memory cells arranged in a plurality of rows and a plurality of columns. A column of the plurality of columns includes a first voltage circuit coupled to internal first nodes of memory cells in the one of the plurality of columns and a second voltage circuit coupled to internal second nodes of the memory cells in the one of the plurality of columns. The first voltage circuit is configured to provide one of a first supply voltage and a second supply voltage lower than the first supply voltage to the internal first nodes. The second voltage circuit is configured to provide one of a first reference voltage and a second reference voltage higher than the first reference voltage to the internal second nodes.
