Title: Non-volatile semiconductor memory device
Inventor: INOUE SATOSHI
IPC: G06K19/07
Filed: 1983-05-12
Abstract: PURPOSE:To protect element characteristics from deterioration, which is caused by repeatedly performing rewritings, by a method wherein a rewriting voltage on the memory contents of a memory cell is contrived in such a way as to be made to steppedly boost successively. CONSTITUTION:First, a pulse in a rewriting voltage is outputted from a boosting circuit 4 for being set at the first level by a pulse control circuit 5, and, after the lapse of a fixed time, the pulse is converted into such a pulse as to change up to the second level and a impressed on a memory cell array. Carriers to flow through an extremely thin insulating film depends upon the density of current to run and the current density becomes larger the more the traps also become necessary. Accordingly, by bringing the pulse in a rewriting voltage in a stepped state, the deterioration of the element characteristics, which is caused by repeatedly rewriting, can be suppressed low.
