Abstract
A memory circuit includes a plurality of memory cells which are subject to memory access operations. These memory access operations serve to selectively discharge one or more of the bit lines A, Abar, B, Bbar associated with the memory cells . During a subsequent precharge operation serving to restore the precharged voltage levels of the bit lines A, Abar, B Bbar charge sharing is performed between non-accessed bit lines and those which have been accessed and accordingly at least partially discharged. Also the precharging circuits associated with the non-accessed bit lines contribute towards the precharging operation.
