Semiconductor memory device and method of manufacturing the same

A contact connected to a word line is formed on a gate electrode of an access transistor of an SRAM cell. The contact passes through an element isolation insulating film to reach an SOI layer. A body region of a driver transistor and that of the access transistor are electrically connected with each other through the SOI layer located under the element isolation insulating film. Therefore, the access transistor is in a DTMOS structure having the gate electrode connected with the body region through the contact, which in turn is also electrically connected to the body region of the driver transistor. Thus, operations can be stabilized while suppressing increase of an area for forming the SRAM cell.

Semiconductor storage device

In a semiconductor storage device that includes memory cells each constituted by one transistor, two adjacent bits of the memory cells form a diffusion pattern (4), two adjacent transistors share a common source region, and the two drain regions are separated from each other. A plurality of arrays (120, 130) each including at least one line of the diffusion patterns (4) have bit lines that are independent for each array. In addition, end portions of the bit lines for each array are located on the two drain regions separated from each other with the common source regions interposed therebetween in one diffusion pattern (4) at an array-dividing border portion. With this, the area can be reduced while a sufficient separation width between the bit lines can be ensured.
