Abstract
This application discloses a memory circuit. Each row of cells includes M+1 bit cells. First to Mth bit cells normally store M-bit data; an (M+1)th bit cell stores opposite data of an ith bit cell; each row of sense amplifiers includes M sense amplifiers; one positive input end of an ith sense amplifier is connected with an output end of the ith bit cell; one negative input end of the ith sense amplifier is connected with an output end of the (M+1)th bit cell; two positive input ends of a jth sense amplifier are connected with an output end of a jth bit cell; two negative input ends of the jth sense amplifier are respectively connected with an output end of the (M+1)th bit cell and an output end of the ith bit cell. The memory circuit can improve data retention and increase the utilization rate of the cells.
