Title: Memory cell
Inventor: IWAHASHI MASAYUKI
IPC: G11C11/413
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To improve the originally low yield of RAMs to enable the stable production by enhancing the back bias dependent of each MOS in a memory cell to control the potential thereof. SOLUTION: A common drain is separated, using the trench isolation such as U-trench and DMOS and TMOS drains are fed at separate wells to suppress the memory cell area expansion. In the memory cell, to increase the back bias dependent of TMOS in view of the process, it is structured such that the back bias potential can be switched over by a fuse or external signal. When the stability of the memory cell is not ensured or read time is long due to lowering of the read current, the back bias potential of TMOS is switched to control so as to ensure the stability of the cell or reduce the read time.

Filed: 1988-07-22
Abstract: PURPOSE:To avoid the troublesome patrol jobs of the maintenance engineers by using a PROM, a rewriting circuit and a circuit storing the program revision codes and surly rewriting a control program via a maintenance terminal and a communication circuit. CONSTITUTION:An instruction requesting a revision mode is received by a maintenance/control processor 1 from a maintenance terminal 4 and then sent to a control circuit 15 via an interface circuit 14. A terminal 4 receives a confirmation signal from the circuit 15 and requests the revision code for a control program stored presently in a PROM 11. Then the circuit 15 reads the revision code out of a code memory circuit 13 and sends it to the terminal 4 via the circuit 14. The terminal 4 selects the data necessary for rewriting and sends them for each block, and the circuit 15 writes these data into the designated position of the ROM 11 via a rewriting circuit 12. Then the terminal 4 stores the revision code in the circuit 13 after the rewrite data is transmitted.
