Title: Driving method for non-volatile semiconductor memory
Inventor: OTANI SHIGEHIRO
IPC: G11C16/02
Filed: 2001-05-17
Abstract: PROBLEM TO BE SOLVED: To lighten stress applied to a main bit line discharge transistor and a select-transistor at the time of erasure. SOLUTION: At the time of erasure, a main bit line discharge signal CPO is made Vss, a main bit line is made a floating state. Next, a source selection gate signal SSG and a drain selection gate signal DSG is made intermediate voltage Vleg (<(Vds+Vth)). Then, a common source line, a local source line, a main bit line, and a local bit line are made a semiconductor-conduction state. Next, a substrate signal SUB and a source line signal CSL are made Vds. And threshold voltage is dropped and erasure operation is performed by making a level of the word line Vneg. In that case, as the main bit line is charged and raised to Vmbl (=Vleg-Vth(ST)), potential difference between a drain and a source of a select-transistor and a main bit line discharge transistor is made lower, and stress can be lightened.
