US 2026/0100214 A1 · SEMICONDUCTOR MEMORY DEVICE AND INITIALIZATION METHOD THEREOF

Abstract

A semiconductor memory device and an initialization method thereof are provided. The semiconductor memory device includes a memory array, a refresh controller, and an initialization controller. The memory array has a plurality of equalize circuits and N memory cells. The equalize circuits are respectively coupled to the N memory cells via a plurality of bit line pairs. The refresh controller is configured to refresh initial data in sequence to the N memory cells according to an auto-refresh command. The initialization controller is configured to perform an initialization operation according to an initialization activation command. The initialization controller enables the equalize circuits and periodically generates the auto-refresh command during the initialization operation.
