Serial Presence Detect (SPD)
In a more technical view,
HSDRAM incorporates very sophisticated memory timings to reach
these speeds. HSDRAM
is a higher performing version of the SDRAM standard.
HSDRAM offers a lower latency and a faster clock access
time than regular SDRAM.
The HSDRAM has the much touted
4.6ns clock access time to give greater performance and
stability at the 133MHz memory speed.
Most of the other PC-133 memory that you buy, will most
likely come with 3:3:3 suggested clock timings, HSDRAM PC-133
comes with 3:2:2 memory timings.
Lower values give better
memory performance while higher values give better stability.
These timings are 3 for column access strobing (CAS), 2
for the row access strobing to column access strobing delay
(RAS to CAS), and 2 for the precharge delay.
Another factor that helps in
the stability of HSDRAM is the 6-layer printed circuit board
(PCB). This helps
keep out and prevent any line noises that may interfere with
