So next time someone tells you "RAM can be accessed at a granularity of one bit", remember that's not really true. It actually uses huge pages just like Flash, which is fundamental when memory is organized as a big 2D array (the page size is one dimension). (4/4)
Addendum: I meant 64 kibibits (64 Kibits or 64Kib) in my original tweet, not 64 kibibytes. It's usually something like 8 bits per chip × 8 chips = 64 bits for a whole DIMM, and pages (rows) are 1024 addresses within each bank, so 65536 bits.
btw, good visualisation of how ram works is here:https://codegolf.stackexchange.com/questions/11880/build-a-working-game-of-tetris-in-conways-game-of-life/142675#142675 …
Not really, once a row is open you can write into it with byte granularity, and closing the row is just disconnecting the bitlines. Only row opening is destructive, and the lower voltages are fixed in dozens of nanoseconds for the whole row (64K in parallel) by the sense amps.
