Abstract
The semiconductor integrated circuit device includes: a first latch which can hold an output signal of the X decoder and transfer the signal to the word driver in a post stage subsequent to the X decoder; a second latch which can hold an output signal of the Y decoder and transfer the signal to the column multiplexer in the post stage subsequent to the Y decoder; and a third latch which can hold an output signal of the sense amplifier and transfer the signal to the output buffer in the post stage subsequent to the sense amplifier. The structure makes it possible to pipeline-control a series of processes for reading data stored in the non-volatile semiconductor memory, and enables low-latency access even with access requests from CPUs conflicting.
