PURPOSE:To provide the memory device where a time element can be registered. CONSTITUTION:The offset for the time constant of an RC circuit RC is set with an input voltage, and a threshold element Th is driven by the charging voltage of a capacitance C1 in the RC circuit RC, and the output of the threshold element Th is used as a stop signal of a digital counter, and a reference voltage input RP is used as a starting signal of the digital counter. The time between the starting signal and the stop signal is held in the digital counter as the digital counted value. |
