Notes: 1. V DD = 1.5V ±0.075mV, V DDQ = V DD, V REF = V SS, f = 100 MHz, T C = 25°C. V OUT(DC) = 0.5 ×<br />

V DDQ, V OUT = 0.1V (peak-to-peak).<br />

2. DM input is grouped with I/O pins, reflecting the fact that they are matched in loading.<br />

3. Includes TDQS, TDQS#. C DDQS is for DQS vs. DQS# and TDQS vs. TDQS# separately.<br />

4. C DIO = C IO(DQ) - 0.5 × (C IO(DQS) + C IO(DQS#)).<br />

5. Excludes CK, CK#; CTRL = ODT, CS#, and CKE; CMD = RAS#, CAS#, and WE#; ADDR =<br />

6. C DI_CTRL = C I(CTRL) - 0.5 × (C CK(CK) + C CK(CK#)).<br />

7. C DI_CMD_ADDR = C I(CMD_ADDR) - 0.5 × (C CK(CK) + C CK(CK#)).<br />
