Notes:
1. Maximum possible skew between a data strobe (MDQS[n]) and any corresponding bit of data (MDQ[8n + {0...7}] if
MDQS—MDQ/MECC input skew per byte
Notes:
1. AC timing values are based on the DDR data rate, which is twice the DDR memory bus frequency.
2. Maximum possible skew between a data strobe (MDQS[n]) and any corresponding bit of data (MDQ[8n + {0...7}] if
0 ≤ n ≤ 7) or ECC (MECC[{0...7}] if n = 8).
