ABSTRACT:
Embodiments of the invention are generally directed to systems, methods, and apparatuses for in-band data mask bit transmission. In some embodiments, one or more data mask bits are integrated into a partial write frame and are transferred to a memory device via the data bus. Since the data mask bits are transferred via the data bus, the system does not need (costly) data mask pin(s). In some embodiments, a mechanism is provided to enable a memory device (e.g., a DRAM) to check for valid data mask bits before completing the partial write to the DRAM array.
