Title: Nonvolatile semiconductor storage
Inventor: HAYAKOSHI MASANORI
IPC: G11C16/06
Filed: 1989-11-07
Abstract: PURPOSE:To sense the memory cells put on the same word line and at the same time to read out data at a high speed in a page mode by providing a sense amplifier on each bit line. CONSTITUTION:A sense amplifier 8 sets the potential of a node N1 at an H level and the potential of a node N2 at an L level respectively. When a memory transistor M1 is set in an erasion state, a bit line 1 is set in an L floating state equal to the state of the N2. However the unbalanced capacity is caused, that is, the capacity of the N1 is larger than that of the N2 by an amount equivalent to the connection of a bit line 1. Thus the potential of the N1 is set at an L level by the amplifier 8 with the potential of the N2 set at an H level respectively. The data are read out via those mentioned operations and the read data are latched by the amplifier 8.
