Title: Nonvolatile semiconductor memory
Inventor: KOBAYASHI SHINICHI
IPC: H01L29/792
Filed: 1988-12-13
Abstract: PURPOSE:To collectively erase memory cells by providing a means, which increases the frequencies of a time constant determining circuit to determine the leading edge time constant of a potential VPP that erases the memory cell of a semiconductor memory at the time of collective erasing. CONSTITUTION:When the frequencies, which determine the time constant to control the leading edge of the VPP in order to erase the memory cell of a memory, are collectively erased, the frequencies are set larger than those to erase the memory cell byte by byte. That is, pulses phib' and phi'b' generated from a dividing circuit (n-1) are outputted through a transfer gate, and the frequencies to determine the leading edge time constant of the VPP at the time of the collective erasing is doubled to the frequencies at the time of normal byte by byte erasing. Consequently the leading edge time constant of the VPP becomes smaller at the time of collective erasing, and the same leading edge time constant as that at the time of byte by byte writing can be obtained. Thus, the period of the output of the VPP potential becomes the same as that of the byte by byte erasing, and the collective erasing of the memory can be excellently executed.
