Abstract:
A page buffer circuit in a memory device includes a logic element configured to perform a series of calculations pertaining to one or more memory access operations and generate a plurality of calculation results associated with the series of calculations and a dynamic memory element coupled with the logic element and configured to store the plurality of calculation results. The page buffer circuit further includes an isolation element coupled between the logic element and the dynamic memory element, the isolation element to permit a calculation result from the logic element to pass to the dynamic memory element when activated and one or more bitline driver circuits coupled to the dynamic memory element and configured to perform pre-charging operations associated with the one or more memory access operations and based at least in part on the plurality of calculation results stored in the dynamic memory element. The one or more bitline driver circuits can perform a first pre-charging operation on the memory array based at least in part on a first calculation result stored in the dynamic memory element during a first period of time when the isolation element is deactivated to disconnect the logic element from the dynamic memory element, and the logic element is configured to concurrently generate a second calculation result during the first period of time.
