Abstract
Memory devices are provided. In an embodiment, a memory device includes a static random access memory (SRAM) array. The SRAM array includes a static random access memory (SRAM) array. The SRAM array includes a first subarray including a plurality of first SRAM cells and a second subarray including a plurality of second SRAM cells. Each n-type transistor in the plurality of first SRAM cells includes a first work function stack and each n-type transistor in the plurality of second SRAM cells includes a second work function stack different from the first work function stack.
