DRAM WITH QUICK RANDOM ROW REFRESH FOR ROWHAMMER MITIGATION

Abstract:

A DRAM memory controller is provided that identifies a marker command directed to a given row in a DRAM. If a threshold probability is satisfied in response to an identification of the marker command, the DRAM memory controller commands the DRAM to refresh a neighboring row in the DRAM. The neighboring row may be a neighboring of the given row or of a recently-closed row.
