DDR2 , Whats DDR2? Like PC2-3200

 

[thehacker11]

double data rate 2...its a new type of ddr

 

[SpookedJunglist]

is there gonna be 184pin ddr2???
any binnefits??

Better signal integrity for higher clock speeds thanks to new features at chip level, such as Off-Chip Driver calibration (OCD) and On-Die Termination (ODT) Larger 4-bit
prefetch, additive latency, and enhanced registers.

EDIT and rep me if i was helpful

DDR2 is the next step to higher performance DDR technology. DDR2 can boost designs with greater clock frequency and available bandwidth without increasing power consumption.

EDIT:

• VDD = 1.8V, VDDQ = 1.8V
• I/O = SSTL_18
• 400 Mb/s/pin and 533 Mb/s/pin data rates
• 3,200 MB/s and 4,300 MB/s for 64-bit systems
• 4n data prefetch
• 4 banks for 256Mb and 512Mb densities
• 8 banks for 1Gb and 2Gb densities
• Burst length of 4 or 8
• WRITE latency = READ latency - 1 clock
• Differential data strobe option
• Duplicate RDQS data strobe option
• READ latency: 3, 4, and 5
• Posted CAS# additive latency: 0, 1, 2, 3, and 4 clocks
• On-die termination (ODT)
• Off-chip driver (OCD) output impedance calibration option
• Pb-free FBGA packaging

thanks for the info
Reps given

heh read what i just edited up there

thanks first rep i got

EDIT: hehe forgot one more thing:
Posted CAS and Additive Latency
These two, prevent data collisions within the memory while still able to transfer more read/write instructions per clock cycle.

Off Chip Driver Calibration
Increases signal integrity
