Memory device with staggered access

Abstract

A memory device supports low power operation by facilitating staggered access to row segments within a row of a memory bank. Upon receiving an activate command to activate a row, the memory device sequentially activates a plurality of local wordlines associated with the row with a stagger interval between activations. Upon receiving an access command associated with the activated row, the memory device sequentially initiates column operations for respective row segments with the same stagger interval between the column operations. The memory device may furthermore facilitate error correction code operations in a staggered manner by sequentially performing computations associated with the different row segments.
