Abstract

See full text

A method and a storage system are provided for implementing enhanced solid state storage class memory (eSCM) including a direct attached dual in line memory (DIMM) card containing Dynamic Random Access Memory (DRAM), and at least one 5 non-volatile memory, for example, Phase Change Memory (PCM), Resistive RAM (ReRAM), Spin-Transfer-Torque RAM (STT-RAM), and NAND Flash chips. An eSCM processor controls selectively allocating data among the DRAM, and the at least one non-volatile memory primarily based upon a data set size.
