Abstract
Methods, devices, and systems for managing memory devices are provided. In one aspect, a memory system can include a memory device including memory cells, a memory controller coupled to the memory device, a power loss protection (PLP) circuit, and a discharge circuit coupled to an output of the PLP circuit. The discharge circuit includes one or more discharge paths configured to discharge at least one of the PLP circuit, the memory device, or the memory controller.
Claims20
A memory system, comprising:
- a memory device comprising memory cells,
- a memory controller coupled to the memory device,
- a power loss protection (PLP) circuit, and
- a discharge circuit coupled to an output of the PLP circuit, wherein the discharge circuit comprises one or more discharge paths configured to discharge at least one of the PLP circuit, the memory device, or the memory controller.
1 more element
A memory system, comprising:
- a memory device comprising memory cells,
- a memory controller coupled to the memory device,
- a power loss protection (PLP) circuit configured to provide power for the memory system when an external power source is turned off, and
- a discharge circuit configured to:
- in response to determining that an output voltage of the PLP circuit is lower than a first threshold, discharge at least one of the PLP circuit, the memory device or the memory controller.
2 more elements
A method of discharging a memory system, comprising:
- in response to determining that an output voltage of a power loss protection (PLP) circuit of the memory system is lower than a first threshold, discharging, by a discharge circuit, at least one of the PLP circuit, a memory device of the memory system, or a memory controller of the memory system,
- wherein the discharge circuit is distanced from the PLP circuit.
