Abstract
Embodiments of the invention are generally directed to systems, methods, and apparatuses for transferring data mask bits to a memory device. In some embodiments, an integrated circuit includes logic to issue a partial write command to a memory device. In addition, the integrated circuit may include logic to transfer a write frame to the volatile memory device over an N bit wide data bus, wherein the write frame includes one or more data mask bits to be transferred over the N bit wide data bus.
Claims20
An integrated circuit comprising:
- logic to issue a partial write command to a volatile memory device;
- and
- logic to transfer a write frame to the volatile memory device over an N bit wide data bus, wherein the write frame includes one or more data mask bits to be transferred over the N bit wide data bus.
A volatile memory device comprising:
- input/output circuitry to receive a write frame from an N bit data bus, wherein the write frame includes one or more data mask bits and further wherein the write frame includes M user interval (UI) transfers, UI 0 through UI M−1, and the one or more data mask bits are transferred during UI 0;
- and
- for each UI, a 2:1 multiplexer to decode the write frame as either a normal write frame or a partial write frame.
A method comprising:
- issuing a partial write command to a volatile memory device;
- and
- transferring a partial write frame to the volatile memory device over an N bit wide data bus, wherein the partial write frame includes one or more data mask bits.
