Abstract: PURPOSE:To use both memories of a DRAM and an SRAM by the constitution of a single control circuit by switching the read/write operation of the DRAM and the read/write operation of the SRAM by only two port signals of a CPU. CONSTITUTION:By a start signal S1 and a control signal S2 of a CPU, a circuit TM1 generates a read/write signal S3 of a DRAM, a circuit TM2 generates a refresh signal S4 of the DRAM, and a circuit TM3 generates a read/write signal S5 of an SRAM. Subsequently, a multiplexer MP1 generates a signal S3, and a signal S4, when a port signal P1 of the CPU is L, and when it is H, respectively, to an operating signal S6 of the DRAM. Also, a multiplexer MP2 selects the signal S6 and the signal S5, when a port signal P2 of the CPU is L, and when it is H, respectively. Therefore, when the signals P1, P2 are both L, the signal S3 is outputted to an output signal S7 of the MP2. Also, when the signal P2 is L and the P1 is H, the signal S4 is outputted to the signal S7. Moreover, when the signal P2 is H, the signal S5 is outputted.

Title: Lateral field effect transistor and manufacture thereof
Inventor: KITAMURA AKIO
IPC: H01L21/336
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To enhance the punch-through breakdown strength in a high- breakdown strength and low-on resistance lateral field effect transistor and to lesson the tradeoff between the breakdown voltage and on resistance of the transistor. SOLUTION: A p-type offset region 100 for forming a drain drift region is duplicated close to a p-type drain region 104, and the region 106 of a low surface impurity concentration is formed into a structure, wherein the region 106 is overhung from a p-type second offset region 110 to the side near a p-type source region 103. The region 106 is easily depleted, but the overlapped part of both of the regions 106 and 110 is hardly depleted, and the punch-through voltage of a lateral field effect transistor is enhanced. If an impurity diffusion for the region 106 is performed in the entire surface of an element, the on resistance of the transistor can be reduced, and as a mask dislocation margin becomes unnecessary, the microscopic formation of the transistor becomes possible.  A structure, wherein the region 110 is formed only under the lower part of a LOCOS 109, dispenses with a mask formation process for the region 110.
