Abstract
A memory device includes a first static random access memory (SRAM) cell, a second SRAM cell, and a first metal layer. The first SRAM cell includes a first write-port pull-up (PU) transistor and a second write-port PU transistor arranged in a Y-direction, and a first read-port PD transistor and a first read-port PG transistor. The second SRAM cell includes a third write-port PU transistor and a fourth write-port PU transistor arranged in the Y-direction, and a second read-port PD transistor and a second read-port PG transistor. The first and second read-port PD transistors and the first and second read-port PG transistors are arranged in the Y-direction. The first metal layer is over the first SRAM cell and the second SRAM cell. The first metal layer includes a read bit-line conductor extending in the Y-direction and shared by the first SRAM cell and the second SRAM cell.
