DESCRIPTION
TM
Network FCRAM
TM
is Double Data Rate Fast Cycle Random Access Memory. TC59LM814/06CFT are Network
FCRAM
TM
containing 268,435,456 memory cells. TC59LM814CFT is organized as 4,194,304-words

8 bits. TC59LM814/06CFT feature a fully
synchronous operation referenced to clock edge whereby all operations are synchronized at a clock input which
enables high performance and simple user interface coexistence. TC59LM814/06CFT can operate fast core cycle
using the FCRAM
TM
core architecture compared with regular DDR SDRAM.
TC59LM814/06CFT is suitable for Network, Server and other applications where large memory density and low
power consumption are required. The Output Driver for Network FCRAM
TM
is capable of high quality fast data
transfer under light loading condition.
