发明名称 SEMICONDUCTOR MEMORY DEVICE
摘要 In a multiport SRAM memory cell of the present invention, an access transistor of a first port is disposed in a p-type well, and an access transistor of a second port is disposed in a p-type well. The gates of all of transistors disposed in a memory cell extend in the same direction. With the configuration, a semiconductor memory device having a low-power consumption type SRAM memory cell with an increased margin of variations in manufacturing, by which a bit line can be shortened in a multiport SRAM memory cell or an associative memory, can be obtained.
