Title:
SYSTEMS AND METHODS TO CALIBRATE DRAM REFRESH ACCORDING TO TEMPERATURE AND NUMBER OF ERRORS
Document Type and Number:
WIPO Patent Application WO/2016/168602
Kind Code:
A3
Abstract:
A system and method of refreshing dynamic random access memory (DRAM) are disclosed. A device includes a DRAM, a bus, and a system-on-chip (SOC) coupled via the bus to the DRAM. The SOC is configured to refresh the DRAM at a particular refresh rate based on a temperature of the DRAM and based on calibration data determined based on one or more calibration tests performed while the SOC is coupled to the DRAM.
