Bidirectional data strobe (DQS) option
Differential clock inputs (CK and CK#)
DLL to align DQ and DQS transitions with CK
Programmable burst: length (2, 4, 8)
Programmable READ# latency (CL): 2 and 2.5
(clock)
Serial Presence Detect (SPD) with EEPROM
Auto and self refresh: 64ms/ 8,192 cycle refresh
Gold edge contacts
Dual Rank

Notes:
1. Includes ± 25mV margin for DC offset on VREF, and a combined total of ± 50mV margin for all AC noise and DC offset on VREF, bandwidth limited to 20MHz. The DRAM must
accommodate DRAM current spikes on VREF and internal DRAM noise coupled to VREF, both of which may result in VREF noise. VREF should be de-coupled with an inductance of ≤ 3nH.
2. VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set equal to VREF, and must track variations in the DC level of VREF
3. VID is the magnitude of the difference between the input level on CK and the input level on CK#.
4. These parameters should be tested at the pin on actual components and may be checked at either the pin or the pad in simulation. The AC and DC input specifications are relative
to a VREF envelop that has been bandwidth limited to 200MHz.
