Faster than DRAM from the 90's.

The access time has actually not changed a lot, it's just that transferring the smallest read a contemporary processor would issue - one cache line (~64 bytes) - at somewhere between 500-1000 MB/s takes around 100 ns already. That transfer-related latency has been reduced drastically.

Didn't /RAS timing drop from like 120ns to 10ns too? That's what I was thinking about. Then DDR, and that bus size is also 16 times wider.

Wasn't tRAS always around 2-3x tCL?

Modern SSDs generally have more bandwidth than DDR2.
