Abstract
Various aspects are described herein. In some aspects, the present disclosure provides a method of communicating data between an electronic unit of a system-on-chip (SoC) and a dynamic random access memory (DRAM). The method includes initiating a memory transaction corresponding to first data. The method includes determining a non-unique first signature and a unique second signature associated with the first data based on content of the first data. The method includes determining if the non-unique first signature is stored in at least one of a local buffer on the SoC separate from the DRAM or the DRAM. The method includes determining if the unique second signature is stored in at least one of the local buffer or the DRAM based on determining the non-unique first signature is stored. The method includes eliminating the memory transaction with respect to the DRAM based on determining the unique second signature is stored.
