Abstract
PURPOSE: To shorten an access time by setting the threshold voltage of the switching transistor (TR) of a bit line selecting decoder lower than that of the TR of a peripheral circuit.
CONSTITUTION: The peripheral circuit is connected to a memory array 1 formed by connecting plural switching TRs Q2 in series through the bit line selecting decoder 2 which has plural shunt circuits selecting bit lines of the memory array, and the threshold voltage of the switching TR Q2 of the bit line selecting decoder 2 is set lower than the threshold voltage of the TR of the peripheral circuit. Their on-resistances are therefore reduced and even a mass storage device wherein the number of switching TRs Q2 of the bit line selecting decoder 2 increases is reduced in the load on a discharging path passed through the bit line selecting decoder 2 when a memory TR Q1 of the memory; array 1 is on. Consequently, the access time of even the mass storage device can be shortened.
