NOTE:
1. Device latencies used for SPD values.
2. The value of tRAS used for -262/-26A/-265 modules is calculated from tRC - tRP. Actual device spec value is 40 ns.
3. The JEDEC SPD specification allows fast or slow slew rate values for these bytes. The worst-case (slow slew rate) value is
represented here. Systems requiring the fast slew rate setup and hold values are supported, provided the faster mini-
mum slew rate is met.
