Overview  
The EM6A9160 SDRAM is a high-speed CMOS  
double data rate synchronous DRAM containing 128  
Mbits. It is internally configured as a quad 2M x 16  
DRAM with a synchronous interface (all signals are  
registered on the positive edge of the clock signal, CK).  
Data outputs occur at both rising edges of CK

burst oriented; accesses start at a selected location  
and continue for a programmed number of locations in  
a programmed sequence. Accesses begin with the  
registration of a BankActivate command which is then  
followed by a Read or Write command. The EM6A9160  
provides programmable Read or Write burst lengths of  
2, 4, or 8. An auto precharge function may be enabled  
to provide a self-timed row precharge that is initiated at  
the end of the burst sequence. The refresh functions,  
either Auto or Self Refresh are easy to use. In addition,  
EM6A9160 features programmable DLL option. By  
having a programmable mode register and extended  
mode register, the system can choose the most  
suitable modes to maximize its performance. These  
devices are well suited for applications requiring high  
memory bandwidth and high performance.
