Functional Description  
The A416316B is a high performance CMOS Dynamic  
Random Access Memory organized as 65,536 words X  
16 bits. The A416316B is fabricated with advanced  
CMOS technology and designed with innovative design  
techniques resulting in high speed, extremely low power  
and wide operating margins at component and system  
levels.

All inputs are TTL compatible. Fast Page Mode  
operation allows random access up to 256 X 16 bits  
within a page, with cycle time as short as 19/21/23 ns.  
The A416316B features a high speed page mode  
operation in which high speed read, write and read-write  
are performed on any of the bits defined by the column  
address. The asynchronous column address uses an  
extremely short row address capture time to ease the  
system level timing constraints associated with  
multiplexed addressing. Output is tri-stated by a column  
The A416316B is best suited for graphics, digital signal  
processing and high performance peripherals.  
The A416316B is available in JEDEC standard 40-pin  
plastic SOJ package and 40/44 TSOP type II package.
