Title:
TEMPERATURE-BASED MEMORY MANAGEMENT
Document Type and Number:
WIPO Patent Application WO/2021/035436
Kind Code:
A1
Abstract:
A memory device and method of operation are described. The memory device may include memory cells of a first type that each store a single bit of information and memory cells of a second type that each store multiple bits of information. The memory cells of the first type may be more robust to extreme operating conditions than the second type but may have one or more drawbacks (e.g., lower density). The memory device may identify data to be written, and in response, may identify a temperature of the memory device. If the temperature is within a nominal operating range associated with a low risk of memory errors, the memory device may write the data to the memory cells of the second type. If the temperature is outside the nominal operating range, the memory device may write the data to the memory cells of the first type.
