Summary:A semiconductor storing apparatus capable of suppressing a peak current in a pre-charge operation and shortening a sense time is provided, includes: a pre-charge method of a bit line of a NAND type flash memory turning on a transistor (BLPRE) and supplying a pre-charge voltage to a sense node (SNS) in time (t1), turning on a transistor (BLCLAMP) connecting to the sense node (SNS) and generating a clamping voltage and turning on a transistor (BLCN) connecting to a node (BLS) in time (t2), turning on a transistor (BLSe/BLSo) connecting between the node (BLS) and a bit line (GBLe/GBLo) in time (t3), and performing the pre-charge operation on the bit line.
