    Abstract: A memory is provided with a pair of banks including a first bank of bitcells and a second bank of bitcells. An I/O circuit for the pair of banks includes a shared write path configured to couple a write driver input signal to the first bank of bitcells responsive to an assertion of a write enable signal for the first bank of bitcells and to couple the write driver input signal to the second bank of bitcells responsive to an assertion of a write enable signal for the second bank of bitcells. The I/O circuit also includes a shared read path configured to couple a data bit output signal from the first bank of bitcells to a sense amplifier responsive to a de-assertion of the write enable signal for the first bank of bitcells and to couple a data bit output signal from the second bank of bitcells to the sense amplifier responsive to a de-assertion of the write enable signal for the second bank of bitcells. The shared read and write paths are further configured to operate simultaneously so that a write operation to one of the banks may occur while a read operation occurs to another one of the banks.
