PURPOSE:To increase read-out operational speed of a sense amplifier. CONSTITUTION:An ON resistor having fully larger resistance than a transistor Tr32 and a transistor Tr33 having current driving capability of the same extent as the Tr32 are provided between a source of the transistor Tr32 forming a level holding circuit with an inversible amplifier IV31 and a power supply potential VDD. A gate length of the transistor Tr32 is made as short as possible in a possible range. Thereby, gate capacity of the transistor Tr32, that is, load capacity of the inversible amplifier IV31 is made small and read-out operational speed is increased. |
