FPGA SRAM

[Carlos]

Hi,

Does anyone know how much SRAM is available on the XILINX XC2S300E SPARTAN
IIE FPGA? Am I right in thinking it's 8096K Bytes? I'm planning on using
the RAM32X1S module, I was wondering how many can I have inside a single
FPGA.

Thanks for any help,

Sorry to disappoint you:
The XC2S300E has 16 BlockRAMs, each of which has 4096 bits, for a total of 64K
bits.
There are also over 6000 Look-Up Tables, each of which can be configured as a
16-bit RAM.
If you need 8 megabytes of RAM, you have to go off-chip. This applies to any
FPGA from any manufacturer. FPGA chip area is too precious for such large
memories.
