Title: Nonvolatile semiconductor memory device
Inventor: KAWAMATA NOBORU
IPC: H01L21/8247
Filed: 1987-05-25
Abstract: PURPOSE:To reduce the power consumption by adding a circuit for executing a control so that a boosting circuit does not operate at the time of rise of a power source, operates only at the time of write/erasion, and a second voltage is generated. CONSTITUTION:When the power becomes ON, the potential of a connecting point 12 of a power-ON reset circuit 8 ascends gradually by a time constant determined by a resistance 9 and a capacity 10 from a ground level. Until the potential of the connecting point 12 reaches a threshold voltage of an inverter 11, the inverse of CON of a control signal from the inverter 11 remains an H level. In this case, an output 2 of a NOR gate 1 becomes an L level, and from a NAND gate 3, no clock CLK is outputted. When the potential of the connecting point 12 exceeds the threshold voltage, the inverse of CON becomes L, and in case when write/erasion are not executed, the inverse of W+E becomes H, the output of the gate 1 is L and the CLK is not outputted to a boosting circuit 6 from the gate 3. In case of executing write/erasion, the CLK is supplied, the boosting circuit 6 operates and the second voltage 7 is outputted, and write/erasion of an EPROM can be executed.
