Description
The the EDD5108AD and the EDD5116AD are 512M
bits Double Data Rate (DDR) SDRAM. Read and write
operations are performed at the cross points of the CK
and the /CK. This high-speed data transfer is realized
by the 2 bits prefetch-pipelined architecture. Data
strobe (DQS) both for read and write are available for
high speed and reliable data bus design. By setting
extended mode register, the on-chip Delay Locked
Loop (DLL) can be set enable or disable.

Electrical Specifications
•
All voltages are referenced to VSS (GND).
•
After power up, wait more than 200 µs and then, execute power on sequence and CBR (Auto) refresh before
proper device operation is achieved.

VDDQ must be lower than or equal to VDD.
VIH is allowed to exceed VDD up to 3.6V for the period shorter than or equal to 5ns.
VIL is allowed to outreach below VSS down to –1.0V for the period shorter than or equal to 5ns.
VIN (DC) specifies the allowable DC execution of each differential input.
VID (DC) specifies the input differential voltage required for switching.
VIH (CK) min assumed over VREF + 0.18V, VIL (CK) max assumed under VREF – 0.18V
if measurement.
