Abstract

A memory system including a plurality of memory chips is provided. The memory system includes a first memory chip and a second memory chip that share a data bus and become active by a chip enable signal, and a controller transmitting multi chip select commands to the first and second memory chips. The first memory chip, in response to the first multichip select command, receives a first operation request transmitted by the controller through the data base, and the second memory chip, in response to the second multichip select command, receives a second operation request transmitted by the controller through the data bus before the first memory chip operates according to the first operation request.
