SEMICONDUCTOR MEMORY DEVICE, MEMORY SYSTEM AND METHOD OF OPERATING THE SAME

摘要

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.

主权项

1. A memory system comprising:
a first memory chip configured to become active in response to a chip enable signal; a second memory chip configured to become active in response to the chip enable signal and configured to share a data bus with the first memory chip; and a controller connected to the first memory chip and the second memory chip in common through the data bus and configured to transmit a first multichip select command and a second multichip select command through the data bus, wherein the first memory chip, in response to the first multichip select command, receives a first operation request transmitted by the controller through the data bus; and wherein 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.
