Abstract
A memory system and an operating method thereof are provided. The memory system includes a plurality of pseudo static random access memory chips and a memory controller. The pseudo static random access memory chips are coupled to each other. When receiving an action command, each of the pseudo static random access memory chips determines whether a refresh collision occurs in itself, and generates a collision signal accordingly. The memory controller controls the pseudo static random access memory chips according to the collision signal. All of the pseudo static random access memory chips share their respective collision signals to perform a same latency synchronously.
