Abstract
A memory device is provided. The memory device includes a pseudo static random access memory (PSRAM), a word line (WL) arbitrator and a refresh controller. The WL arbitrator receives a WL signal and segments the WL signal according to a burst length setting value, to obtain a segmented WL signal. In a synchronous mode, the refresh controller provides a first refresh trigger signal corresponding to the WL signal to refresh the PSRAM. In a smart refresh mode, the refresh controller provides a second refresh trigger signal corresponding to the segmented WL signal to refresh the PSRAM.
