Volatile Memory Erasure through Various Methods

March 25, 2020


Enhancing data security in cloud computing

Technology Overview

Critical security and data privacy issues can exist if the dynamic random-access memory (DRAM) content is not sanitized or wiped out before being allocated to a newly provisioned virtual machine in cloud computing. Various methods have been developed to erase volatile memory that is comprised of erasure circuitry that prevents refreshment of the memory upon occurrence of a predefined event by the randomization of data stored, by manipulating reference voltage, and by controlling refreshment of stored data.
