Title:
ELECTRONIC CIRCUIT AND BISTABLE CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2020/241000
Kind Code:
A1
Abstract:
Provided is an electronic circuit equipped with: a cell array comprising a plurality of memory cells, each of the memory cells being equipped with a bistable circuit equipped with a first inverter circuit and a second inverter circuit that switch between a first mode in which a transfer characteristic does not substantially have hysteresis and a second mode in which the transfer characteristic has hysteresis, an output node and an input node of the first inverter circuit being connected to an input node and an output node of the second inverter circuit, respectively; and a control circuit that, after one or more first memory cells not required to hold data among the plurality of memory cells are powered off, puts the bistable circuit in the remaining one or more second memory cells among the plurality of memory cells into the second mode, and, while the second mode is being maintained, supplies, to the bistable circuit in one or more second memory cells, second power supply voltage which is lower than first power supply voltage to be supplied to the bistable circuit at the time of reading and/or writing of data and at which the bistable circuit in the second mode can hold the data.
