Table 9-4. EBR based True Dual Port Memory Port Definitions
Reset (or RST) resets only the input and output registers of the RAM. It does not reset the contents of the memory.
Chip Select (CS) is a useful port in the EBR primitive when multiple cascaded EBR blocks are required by the
memory. The CS signal forms the MSB for the address when multiple EBR blocks are cascaded. Since CS is a 3-
bit bus, it can cascade eight memories easily. However, if the memory size specified by the user requires more than
eight EBR blocks, the ispLEVER or Diamond software automatically generates the additional address decoding
logic, which is implemented in the PFU external to the EBR blocks.
Each EBR block consists of 9,216 bits of RAM. The values for x’s (for address) and y’s (data) for each EBR block
for the devices are listed in Table 9-5.
Table 9-5. MachXO Dual Port Memory Sizes for 9K Memory
Table 9-6 shows the various attributes available for the True Dual Port Memory (RAM_DP_TRUE). Some of these
attributes are user-selectable through the IPexpress GUI. For detailed attribute definitions, refer to the Appendix A.
