The SMJ416400 series is a set of high-speed  
16777216-bit dynamic random-access  
4
5
memories (DRAMs), organized as 4194304  
words of four bits each. The series employs  
enhanced performance implanted CMOS  
(EPIC ) technology for high performance,  
reliability, and low power.

These devices feature maximum RAS access  
times of 70 ns, 80 ns, and 100 ns. All inputs,  
outputs, and clocks are compatible with series 54  
TTL. All addresses and data-in lines are latched  
on-chip to simplify system design. Data out is  
unlatched to allow greater system flexibility.
