Title: Nonvolatile semiconductor memory
Inventor: SUDO NAOAKI
IPC: G11C16/02
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a nonvolatile semiconductor memory in which data can be written and erased stably at high speeds even when the writing voltage fluctuates by setting the pulse of a writing pulse to the optimum value by means of a writing pulse generating circuit in response to a supplied pulse width control signal. SOLUTION: When a high voltage VPP becomes a value VPH which is higher than a set value VPO, a voltage detecting circuit 7 outputs an H-level signal F1 and a writing pulse generating circuit 6 outputs a writing pulse P1 having a pulse width TPN shorter than an initialized pulse width TPO. When the high voltage PP becomes another value VPL which is lower than the set value VPO, on the contrary, the voltage detecting circuit 7 outputs an H-level signal F3 and the writing pulse generating circuit 6 outputs a writing pulse P3 having a pulse width TPL which is longer than the initialized pulse width TPO. Therefore, even when the externally inputted high voltage fluctuates after output, the deterioration of writing controllability and writing speed can be minimized.
