Each EBR block consists of 18,432 bits of RAM. The values for x’s (for address) and y’s (data) for each EBR block
for the devices are as in Table 10-9.
Table 10-9. Pseudo-Dual Port Memory Sizes for 16K Memory for LatticeXP2
Table 10-10 shows the various attributes available for the Pseudo-Dual Port Memory (RAM_DP). Some of these
attributes are user-selectable through the IPexpress GUI. For detailed attribute definitions, refer to Appendix A.
