Hello, your question about swapping an HDD for NVRAM and its impact on memory hierarchy is interesting. Let me break it down for you.

Replacing an HDD with NVRAM would shift the storage approach from traditional spinning disks to faster, volatile memory. This change could affect how data is organized and accessed within the system's memory hierarchy.

Whether it’s feasible depends on your specific needs and constraints, but it is possible in certain scenarios. Would you like more details on the technical implications?

NVRAM stands for non-volatile RAM, indicating data stays after power cuts. It tends to be quicker but consumes more power due to additional transistors and components inside the chip, compared to flash memory like NAND. Cost is also higher since it requires more complex fabrication. Some systems already used standard SDRAM or DDR1 modules in SATA drives, storing the data with a battery and 5V from the PCI slot—essentially functioning as a NVRAM drive. Companies like Gigabyte developed such solutions, potentially using up to four DDR1 modules for a SATA device: https://www.gigabyte.com/hr/Press/News/404. Performance was constrained by the SATA interface and the FPGA used, rather than a dedicated chip, and M.2 and PCIe E were not yet available.
