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.
Claims19
An apparatus, comprising:
- a processor configured to:
- determine a charge level of an energy source coupled to the apparatus has fallen below a particular charge level;
- and
- transmit, to a memory device upon determining the charge level of the energy source has fallen below the particular charge level, signaling indicative for the memory device to disable performance of background operations, wherein the background operations whose performance is disabled include wear leveling operations.
A method, comprising:
- determining, by a host, that a charge level of an energy source coupled to the host has fallen below a particular charge level;
- and
- transmitting, from the host to a memory device upon determining the charge level of the energy source has fallen below the particular charge level, signaling indicative for the memory device to disable performance of background operations.
A managed NAND device, comprising:
- a NAND flash memory;
- and
- a controller having control circuitry configured to:
- receive, from a host upon a power level of a battery coupled to the host falling below a particular level, signaling clearing a flag used to enable or disable execution of background operations;
- and
- terminate performance of background operations responsive to receiving the signaling clearing the flag.
