Good point: I-cache is memory too. (Indeed it is SRAM, so its bits might be even more fragile than DRAM!)

- c-c-c-c-c 7mo agoWhy would a 6T cell (SRAM) be more fragile than a 1T1C (DRAM) cell?
- zinekeller 7mo agoBecause it's SRAM, and therefore it still can lose its electrons because we're working with cells a few atoms thick? The loss is not necessarily in L1 (where it's replaced frequently), but in L3 which now has memory comparable to PCs in the early 2000s (and can have its data "stuck" in the same physical area for minutes).
