Abstract
The present disclosure includes apparatuses and methods for providing energy information to memory. An embodiment includes determining, by a host, that a charge level of an energy source coupled to the host has reached or exceeded a threshold value, and transmitting, from the host to a memory device coupled to the host, signaling indicative of an energy mode for the memory device, wherein the signaling is transmitted based at least in part on determining that the charge level of the energy source has reached or exceeded the threshold.
Claims20
A method, comprising:
- determining, by a host, that a charge level of an energy source coupled to the host has fallen below a threshold value;
- transmitting, from the host to a memory device coupled to the host, signaling indicative to turn power loss protection on for the memory device, wherein the signaling is transmitted based at least in part on determining that the charge level of the energy source has fallen below the threshold value;
- and
- performing, by the memory device upon receiving the signaling indicative to turn power loss protection on, an error correction operation on data stored in the memory device that is different than an error correction operation performed on the data prior to the memory device receiving the signaling.
A method, comprising:
- performing, by a memory device, a first error correction operation on data stored in the memory device;
- receiving, by the memory device from a host coupled to the memory device after performing the first error correction operation, signaling indicative to turn power loss protection on for the memory device;
- determining, by the memory device, to perform a power loss protection operation based at least in part on the signaling received from the host;
- performing, by the memory device, the power loss protection operation;
- and
- performing, by the memory device upon performing the power loss protection operation, a second error correction operation on the data stored in the memory device, wherein the second error correction operation is different than the first error correction operation.
A system, comprising:
- a memory device;
- a processor;
- a controller coupled to the processor, wherein at least one of the processor or controller is configured to determine that an energy source coupled with the processor is removable;
- and
- an interface coupled with the controller and configured to transmit, to the memory device, signaling indicative to turn power loss protection on for the memory device, wherein the signaling is transmitted based at least in part on the processor or controller determining that the energy source coupled with the processor is removable;
- wherein the memory device is configured to perform, upon receiving the signaling indicative to turn power loss protection on, an error correction operation on data stored in the memory device that is different than an error correction operation performed on the data prior to the memory device receiving the signaling.
