Abstract
Methods, systems, and devices for managing error control information using a register are described. A memory device may store, at a register, an indication of whether the memory device has detected an error included in or otherwise associated with data requested from a host device. The memory device may determine to store the indication based on whether a communication protocol is enabled or disabled, and whether an error control configuration is enabled or disabled. The host device may request information from the register of the memory device, and the memory device may output the indication of whether the error was detected in response to the request.
Claims19
A method by a memory device, comprising:
- accessing a second register of the memory device that stores a status of a first communication protocol and a status of a first error control configuration;
- determining, at the memory device, that the first communication protocol for reporting information to a host device is enabled or disabled, wherein determining that the first communication protocol is enabled or disabled is based at least in part on accessing the second register;
- determining, at the memory device, that the first error control configuration for reporting a comparison of syndromes generated by the memory device is enabled or disabled, wherein determining that the first error control configuration is enabled or disabled is based at least in part on accessing the second register;
- and
- configuring a register of the memory device to operate in a first mode associated with the first error control configuration based at least in part on determining that the first communication protocol is disabled and the first error control configuration is enabled.
A memory device, comprising:
- a register;
- a second register operable to:
- store a status of a first communication protocol and a status of a first error control configuration;
- and
- circuitry operable to:
- determine that the first communication protocol for reporting information to a host device is enabled or disabled based at least in part on the stored status of the first communication protocol;
- determine that the first error control configuration for reporting a comparison of syndromes generated by the memory device is enabled or disabled based at least in part on the stored status of the first error control configuration;
- and
- configure the register to operate in a first mode associated with the first error control configuration based at least in part on determining that the first communication protocol is disabled and the first error control configuration is enabled.
A method by a host device, comprising:
- writing, by the host device to a first register associated with a memory device, a first indication that a first communication protocol for reporting information from the memory device to the host device is disabled;
- writing, by the host device to the first register, a second indication that a first error control configuration for reporting a comparison of syndromes generated by the memory device is enabled;
- and
- transmitting, to the memory device, a command to read information stored at a second register of the memory device based at least in part on the first communication protocol being disabled and the first error control configuration being enabled and based at least in part on writing the first indication and the second indication to the first register, the information indicating whether a first plurality of syndromes matches a second plurality of syndromes associated with an error control operation performed at the memory device, wherein the information is based at least in part on the first indication and the second indication.
