In a similar vein, why can we not use the technology of RAM to prolong the life-cycle of an SSD?

    In a RAM you’re just trapping current in a loop inside a logical circuit and the state that you get, since it will be stable until it’s reset, is just a memorized 1 bit. You’re not changing anything physical there.

    See: https://en.wikipedia.org/wiki/Memory_cell_(computing) (not an ELI5 though)

    Wikipedia animation of a basic logical circuit that allows you to do that using NOR gates:

    An animation of a SR latch, constructed from a pair of cross-coupled NOR gates.

      That is static RAM (SRAM). Most RAM in computesr is DRAM, which works a bit differently and is much cheaper and denser, but more difficult to operate.
