Semiconductor memory system, semiconductor memory chip, and method of masking write data in a semiconductor memory chip

摘要

In a semiconductor memory chips, a semiconductor memory system, and a method of masking write data, data, command, and address signal streams are serially transmitted in the form of signal frames in accordance with a predefined protocol. The semiconductor memory system and predefined protocol are adapted to transfer write data mask bits in a close relation to respectively associated write data units within one write data/command stream. An interface section between a reception interface and a memory core of the semiconductor memory chip includes a frame decoder and a intermediate data buffer.
