DESCRIPTION
The Synergy SY10/100/101474 are 4096-bit Random
Access Memories (RAMs), designed with advanced Emitter
Coupled Logic (ECL) circuitry. The devices are organized
as 1024-words-by-4-bits and meet the standard 10K/100K
family signal levels. The SY100474 is also supply voltage-
compatible with 100K ECL, while the SY101474 operates
from 10K ECL supply voltage (–5.2V). All feature on-chip
voltage and temperature compensation for improved noise
margin.
The SY10/100/101474 employ proprietary circuit design
techniques and Synergy’s proprietary ASSET advanced
bipolar technology to achieve extremely fast access, write
pulse width and write recovery times. ASSET uses
proprietary technology concepts to achieve significant
reduction in parasitic capacitance while improving device
packing density. Synergy’s circuit design techniques, coupled
with ASSET, result not only in ultra-fast performance, but
also allow device operation with virtually no soft error
sensitivity and with outstanding device reliability in volume
production.
