Abstract
A memory device provides for a multiple-port read operation, and includes an array of bitcells and a control circuit. Each bitcell of the array includes a write wordline port and a first read wordline port. The control circuit provides an output to the write wordline port, and includes as inputs a write select port and a second read wordline port. In a write mode, the control circuit couples the write select port to the output and disables the second read port. In a read mode, the control circuit couples the second read wordline port to the output and disables the write select port, thereby enabling a multiple-port read operation to the array of bitcells.
