Abstract: A method and system for performing byte-writes are described, where byte-writes involve writing only particular bytes of a multiple byte write operation. Embodiments include mask data that indicates which bytes are to be written in a byte-write operation. No dedicated mask pin(s) or dedicated mask line(s) are used. In one embodiment, the mask data is transmitted on data lines and store in response to a write_mask command. In one embodiment, the mask data is transmitted as part of the write command.

Abstract translation: 描述了用于执行字节写入的方法和系统，其中字节写入仅涉及仅写入多字节写入操作的特定字节。 实施例包括指示在字节写入操作中要写入哪些字节的掩码数据。 不使用专用的掩码引脚或专用掩码线。 在一个实施例中，掩码数据在数据线上传输，并响应于write_mask命令存储。 在一个实施例中，掩模数据作为写入命令的一部分被发送。
