Abstract
A semiconductor device includes: a sense amplifier; a branched line selectively connectable to the sense amplifier; a recycling arrangement selectively connectable to the branched line; an array of bit lines connected to corresponding memory cells; a multiplexer configured to selectively connect the branched line to a selected one of the memory cells through a corresponding line amongst the array of bit lines; and a controller. The controller is configured to: permit, during a recovery phase in which a gleaned amount of charge (gleaned charge) is recovered, flow of charge (charge-flow) between the recycling arrangement and the branched line; interrupt, during a drainage phase in which the gleaned charge is preserved, charge-flow between the recycling arrangement and the branched line; and permit, during a reuse phase in which the gleaned charge is reused, charge-flow between the recycling arrangement and the branched line.
