on a 144 pin SO-DIMM multilayer FR4 Substrate.
Auto and Self Refresh capability
LVTTL compatible inputs and outputs
Serial Presence Detect with EEPROM
Fully synchronous: All signals are registered on the
positive edge of the system clock
Programmable Burst Lengths: 1, 2, 4, 8 or Full
Page
3.3V ± 0.3V Power Supply
Dual Rank

Notes:
1. The minimum number of clock cycles is determined by dividing the minimum time required with clock cycle time and then rounding off to the next higher integer.
2. Minimum delay is required to complete write.
3. All parts allow every cycle column address change.
4. In case of row precharge interrupt, auto precharge and read burst stop.

Notes :
1. Parameters depend on programmed CAS latency.
2. If clock rising time is longer than 1ns, (tr/2-0.5)ns should be added to the parameter.
3. Assumed input rise and fall time (tr & tf) = 1ns.
If tr & tf is longer than 1ns, transient time compensation should be considered,
i.e., [(tr + tf)/2-1]ns should be added to the parameter.
