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.
Claims18
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;
- determining, by the host, an age of the energy source;
- transmitting, from the host to a memory device coupled to the host, a single data bit indicating to turn power loss protection on for the memory device, wherein the single data bit is transmitted based at least in part on:
- determining that the charge level of the energy source has fallen below the threshold value;
- and
- the determined age of the energy source;
- and
- performing, by the memory device upon receiving the single data bit indicating 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 single data bit.
A method, comprising:
- determining, by a host, an age of an energy source coupled to the host;
- transmitting, from the host to a memory device coupled to the host, a single data bit indicating to turn power loss protection on or off for the memory device, wherein the single data bit is transmitted based at least in part on the determined age of the energy source;
- determining, by the memory device, whether to perform one or more power loss protection operations based at least in part on the single data bit received from the host;
- performing, by the memory device, the one or more power loss protection operations upon determining to perform the one or more power loss protection operations;
- and
- performing, by the memory device upon performing the one or more power loss protection operations, 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 performing the one or more power loss protection operations.
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 not removable;
- and
- determine an age of the energy source;
- and
- an interface coupled with the controller and configured to transmit, to the memory device, a single data bit indicating to turn power loss protection on or off for the memory device, wherein the single data bit is transmitted based at least in part on:
- the processor or controller determining that the energy source coupled with the processor is not removable;
- and
- the determined age of the energy source;
- wherein the memory device is configured to perform, upon receiving the single data bit indicating 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 single data bit.
