There's different options for different things.
You have:
- EEPROM for low/medium frequency of update, small size, persistence
- NAND flash for low/medium frequency of update, semi-arbitrary size, persistence
- eDRAM variants (Mosys '1T SRAM' comes to mind, which is still DRAM but has more dedicated Row/Column circuitry vs SDRAM's RAS-CAS timing shenanigans) for frequent update, volatile or maybe battery backed storage, non-persistent
Which... we -kinda- see in some layers already, as eDRAM has gone from 'fancy server procs and halo mobile chips' to a -little- more mainstream.
