Abstract
A non-volatile memory core comprises one or more memory bays. Each memory bay comprises one or more memory blocks that include a grouping of non-volatile storage elements. In one embodiment, memory blocks in a particular memory bay share a group of read/write circuits. During a memory operation, memory blocks are transitioned into active and inactive states. The process of transitioning blocks from an inactive state to an active state includes enabling charge sharing between a memory block entering the active state and another memory block that was previously in the active state. This charge sharing improves performance and/or reduces energy consumption for the memory system.
