Memory 

Pipelined ZBTRAM 
Up to 16Mbytes of pipeline ZBT memory is provided with direct access by the FPGA. 
The ZBTRAM is designed to sustain 100% bus bandwidth by eliminating turnaround 
cycle when there is transition from Read to Write, or vice versa. 
This device is well suited for SDR applications that experience frequent bus 
turnarounds, need to operate on small data chunks (especially one-word chunks), 
and need to operate at higher frequencies than permitted by the flow-through 
version. 
The memory is split into 4 independent 16-bit-wide Banks.  
All three chip enables are available on each bank for simple depth expansion with no 
data contention. 
Each bank is composed of one chip, available in 4 different sizes as presented in 
Table 2: ZBTRAM sizes: 
For more complete information, please read:

application
