Methods for providing device status in response to read commands directed to write-only mode register bits and memory devices and systems employing the same

A method, comprising:

• receiving, at a memory device, a mode register read command targeting a mode register bit of a mode register, wherein the mode register bit is a memory device read-only bit combined with a host device write-only bit;
• and
• returning, by the memory device, a status of the memory device during a read of the mode register bit, wherein the status is independent of a value written to the mode register bit.

A memory device, comprising:

• a memory array;
• and
• a mode register configured to store a mode register bit that is a memory device read-only bit combined with a host device write-only bit, wherein the memory device is configured to return a status of the memory device during a read of the mode register bit independent of a value written to the mode register bit by a host device.

A method, comprising:

• transmitting, to a memory device, a mode register read command targeting a mode register bit of a mode register, wherein the mode register bit is a memory device read-only bit combined with a host device write-only bit;
• and
• receiving, from the memory device in response to the mode register read command, a status of the memory device during a read of the mode register bit, wherein the status is independent of a value written to the mode register bit.
