Abstract
A memory device that combines RAM and ROM devices into a single memory array is provided. The memory array includes a memory cell for the RAM that is associated with a first bit line and a first word line. The memory array also includes a second memory cell for the ROM that is associated with a second bit line and a second word line. The first bit line and the second bit line are connected with each other. The second memory cell is provided with a circuit that discharges the second bit line to represent a logical value “0” in response to a signal from the second word line.
