Abstract
Provided are an operating method of a host device, an operating method of a memory device, and a memory system. The operating method of a host device includes transmitting a request command for performing an eye-opening monitor (EOM) operation to a memory device, transmitting a parameter for performing the EOM operation to the memory device, transmitting pattern data for performing the EOM operation to the memory device, and receiving a first response signal including a result of the EOM operation performed based on the parameter and the pattern data from the memory device.
Claims21
A method of operating a host device, the method comprising:
- transmitting, by the host device, a request command for performing an eye-opening monitor (EOM) operation to a memory device;
- transmitting, by the host device, at least one parameter for performing the EOM operation to the memory device;
- transmitting, by the host device, pattern data for performing the EOM operation to the memory device;
- and
- receiving, by the host device, a first response signal including a result of the EOM operation performed based on the at least one parameter and the pattern data from the memory device,
- wherein the EOM operation is performed based on a comparison between a main path signal, which corresponds to a signal received from the host device and restored at the memory device, and an EOM path signal, which corresponds to a signal received from the host device and restored using an offset value at the memory device, and
- wherein the at least one parameter for performing the EOM operation includes a parameter that defines the offset value.
A method of operating a memory device, the method comprising:
- receiving, by the memory device, a request command for performing an eye-opening monitor (EOM) operation from a host device;
- receiving, by the memory device, at least one parameter for performing the EOM operation from the host device;
- receiving, by the memory device, pattern data for performing the EOM operation from the host device;
- and
- performing, by the memory device, the EOM operation based on the at least one parameter and the pattern data and transmitting a first response signal including a result of performing the EOM operation to the host device,
- wherein the performing the EOM operation comprises performing the EOM operation based on a comparison between a main path signal, which corresponds to a signal received from the host device and restored at the memory device, and an EOM path signal, which corresponds to a signal received from the host device and restored using an offset value at the memory device, and
- wherein the at least one parameter for performing the EOM operation includes a parameter that defines the offset value.
A memory system comprising:
- a host device including a host controller;
- and
- a memory device including a device controller and an eye-opening monitor (EOM),
- wherein the host controller is configured to transmit a request command for performing an EOM operation to the memory device, transmit at least one parameter for performing the EOM operation to the memory device, transmit pattern data for performing the EOM operation to the memory device, and receive a first response signal including a result of the EOM operation performed based on the at least one parameter and the pattern data from the memory device,
- wherein the EOM operation is performed based on a comparison between a main path signal, which corresponds to a signal received from the host device and restored at the memory device, and an EOM path signal, which corresponds to a signal received from the host device and restored using an offset value at the memory device, and
- wherein the at least one parameter for performing the EOM operation includes a parameter that defines the offset value.
