SYSTEM AND METHOD FOR CONSERVING POWER CONSUMPTION IN A MEMORY SYSTEM

摘要

Systems and methods are disclosed for conserving power consumption in a memory system. One such system comprises a system on chip (SoC) and an encoder. The SoC comprises one or more memory clients for accessing a dynamic random access memory (DRAM) memory system coupled to the SoC. The encoder resides on the SoC and is configured to reduce a data activity factor of memory data received from the memory clients by encoding the received memory data according to a compression scheme and providing the encoded memory data to the DRAM memory system. The DRAM memory system is configured to decode the encoded memory data according to the compression scheme into the received memory data.

1. A method for conserving power consumption in a memory system, the method comprising:
receiving memory data from one or more memory clients residing on a system on chip (SoC) for accessing a dynamic random access memory (DRAM) memory system coupled to the SoC; reducing a data activity factor defined by the received memory data by encoding the received memory data according to a compression scheme; providing the encoded memory data to the DRAM memory system; and the DRAM memory system decoding the encoded memory data according to the compression scheme into the received memory data.
