In accordance with embodiments of the present disclosure, an information handling system may include a processor and a memory system communicatively coupled to the processor. The memory system may include one or more persistent memory modules, each of the one or more persistent memory modules comprising a volatile memory and a non-volatile memory and one or more health registers accessible to a host system executing on the processor, the health registers storing health information indicating, for each of a plurality of ranks of the volatile memory, whether the memory system can reliably perform a save operation to a portion of non-volatile memory mapped to volatile memory of the rank.

Systems and methods for granular non-volatile memory health visibility to a host

In accordance with embodiments of the present disclosure, an information handling system may include a processor and a persistent memory system communicatively coupled to the processor, the persistent memory system comprising one or more persistent memory modules and a plurality of targeted save registers, each targeted save register associated with a respective portion of the persistent memory system, and each targeted save register having a value indicative of how save operations from volatile memory to non-volatile memory of the persistent memory system are to be performed with respect to the respective portion of the persistent memory system.

Systems and methods for selective save operations in a persistent memory

A non-volatile dual in-line memory module (NVDIMM) includes a dynamic random access memory (DRAM) block, a plurality of non-volatile random access memory (NVRAM) blocks, and an NVDIMM controller. The DRAM block is organized into a number (N) of pages. Each NVRAM block is organized into the number (N) of pages, each page of the DRAM block being N-way set associatively associated with a page of each of the NVRAM blocks. The NVDIMM controller is configured to copy first data from a first page of a first NVRAM block to an associated first page of the DRAM block.

System and method to provide persistent storage class memory using NVDIMM-N with an NVDIMM-P footprint

An information handling system includes a first memory module having a volatile memory, a non-volatile memory, and a save controller configured to execute a save operation that transfers at least all modified information of the volatile memory to the nonvolatile memory. A power-down controller of the information handling system is connected to the first memory module, and includes a first input to receive a first indicator that indicates the first memory module is to perform the save operation, a second input to receive a second indicator that indicates a thermal characteristic of the system, and control circuitry to provide the save operation indicator to the first memory module to initiate the save operation in response to receiving the first indicator.
