Abstract
Systems and methods for monitoring and controlling repetitive accesses to a dynamic random-access memory (DRAM) row are disclosed. A method for monitoring and controlling repetitive accesses to a DRAM can include dividing a bank of the DRAM into a number of logical blocks, mapping each row of the bank to one of the logical blocks, monitoring accesses to the logical blocks, and controlling accesses to the logical blocks based on the monitoring.
