Title:
COUNTER-BASED SELECTIVE ROW HAMMER REFRESH APPARATUS AND METHOD FOR ROW HAMMER PREVENTION
Document Type and Number:
WIPO Patent Application WO/2022/139057
Kind Code:
A1
Abstract:
The present invention relates to a counter-based selective Row Hammer refresh apparatus and method for Row Hammer prevention and, more particularly, to an apparatus and method for reducing energy consumption of dynamic random access memory (DRAM) by improving counter-based algorithms for solving a Row Hammer problem when applying a refresh management (RFM) command that is a new command applied to the latest DRAM standards, such as DDR5, LPDDR5, and the like.
