Title: Nonvolatile semiconductor memory
Inventor: IWAHASHI HIROSHI
IPC: G11C8/10
Filed: 1981-06-12
Abstract: PURPOSE:To further minimizing the memory size and to compact the memory cells to obtain large capacity of the titled memory, by cutting off not-selected cells in either case of data writing and data readout. CONSTITUTION:At the time of data readout, the source electric potential of a transistor T0' rises until the transistor T0' is cut off, and the source electric potential of another transistor T2' (whose threshold electric potential is almost OV), to which the electric potential is gate-inputted, attains almost the same level as the source electric potential of the above mentioned transistor T0'. That is to say, the electric potential Vs at a source connecting point S of the memory cell array rises to a degree which cuts off the threshold voltage of not-selected memory cells in the memory cell array at the time of readout, even when the threshold voltage of the not-selected memory cells is negative. At this time, a transistor T4' is turned on because an R/(-W) signal is ''1'', and a transistor T4 of a voltage applying circuit 31 is turned off because a (-R)/W signal is ''0''.
