Abstract
A wake-up circuit of a memory device employs a cascade chain structure in which bit lines are divided into a plurality of blocks, and if the bit lines of one of the blocks are determined to have undergone a wake-up operation based on a bit line voltage fed back in the block, the wake-up operation is performed on a subsequent block. Accordingly, a wake-up delay can be varied, and therefore peak currents can be controlled, thereby reducing overall system power noise.
