Title:
MEMORY DEVICE, CONTROL METHOD FOR CONTROLLING MEMORY DEVICE, AND PRODUCTION METHOD FOR MEMORY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/220548
Kind Code:
A1
Abstract:
This memory device comprises: a first non-volatile memory die; a second non-volatile memory die that is layered above the first non-volatile memory die; a controller; and first and second temperature sensors included in the first and second non-volatile memory dies, respectively. The controller reads temperatures measured by the first and second temperature sensors from the first and second non-volatile memory dies. If at least one of the temperatures read from the first and second non-volatile memory dies is higher than or equal to a threshold temperature, the controller reduces the frequency of issuance of a command to the first and second non-volatile memory dies or the rate of access to the first and second non-volatile memory dies.
