DESCRIPTION
Network FCRAM
TM
is Double Data Rate Fast Cycle Random Access Memory. TC59LM836DKB is Network
FCRAM
TM
containing 301,989,888 memory cells. TC59LM836DKB is organized as 2,097,152-words
×
4 banks
×
36
bits. TC59LM836DKB 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.
TC59LM836DKB can operate fast core cycle compared with regular DDR SDRAM.
TC59LM836DKB is suitable for Network 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.
