Abstract

A temperature-controlled self-refresh method for a 3D stacked memory and a temperature-controlled self-refresh circuit for a 3D stacked memory; the temperature-controlled self-refresh method includes: measuring the temperature of a memory to be refreshed, and generating an internal refresh rate; receiving an external refresh rate; The refresh rate and the external refresh rate obtain the target refresh rate of the memory to be refreshed; the memory to be refreshed is controlled to be refreshed at the target refresh rate; therefore, this embodiment sets a corresponding internal refresh rate for each memory respectively, combining the internal refresh rate and The external refresh rate can perform balanced adaptive refresh control on the memory to be refreshed, which ensures the data storage security of the 3D stacked memory and improves the reliability and stability of the 3D stacked memory.

Description

technical field [0001] The present application belongs to the technical field of memory control, and in particular relates to a temperature-controlled self-refresh method of a 3D stacked memory and a temperature-controlled self-refresh circuit of a 3D stacked memory. Background technique [0002] With the continuous development of electronic technology, related electronic equipment will generate a large amount of data during operation, so technicians must use storage electronic equipment to completely retain the data output by electronic equipment, thereby ensuring the operation safety of electronic equipment; and electronic equipment The output data is gradually developing in the direction of large capacity, real-time, parallel input and output, then the electronic equipment will generate a large amount of parameters in the working process, correspondingly, the storage device also needs to have large storage capacity, high bandwidth, Low-latency memory access performance; o...
