L67130/L67140  
1 K × 8 CMOS Dual Port RAM 3.3 Volt  
Introduction  
The L67130/67140 are very low power CMOS dual port Using an array of eight transistors (8T) memory cell and  
static RAMs organized as 1024 × 8. They are designed to fabricated with the state of the art 1.0 µm lithography  
be used as a stand-alone 8 bits dual port RAM or as a named SCMOS, the M67130/140 combine an extremely  
combination MASTER/SLAVE dual port for 16 bits or low standby supply current (typ = 1.0 µA) with a fast  
more width systems. The MHS MASTER/SLAVE dual access time at 45 ns over the full temperature range. All  
port approach in memory system applications results in versions offer battery backup data retention capability  
full speed, error free operation without the need for with a typical power consumption at less than 5 µW.  
additional discrete logic.  
For military/space applications that demand superior  
Master and slave devices provide two independent ports  
with separate control, address and I/O pins that permit  
independent, asynchronous access for reads and writes to  
any location in the memory. An automatic power down  
feature controlled by CS permits the onchip circuitry of  
each port in order to enter a very low stand by power  
mode.  
levels of performance and reliability the L67130/67140  
is processed according to the methods of the latest  
revision of the MIL STD 883 (class B or S) and/or ESA  
SCC 9000.
