Chapter 1: Block RAM Resources
Embedded dual- or single-port RAM modules, ROM modules, synchronous FIFOs, and
data width converters are implemented using the Xilinx CORE Generator™ block memory
modules. Dual-clock FIFOs can be generated using the CORE Generator FIFO Generator
module. The synchronous or asynchronous (dual-clock) FIFO implementation does not
require additional CLB resources for the FIFO control logic because it uses dedicated
hardware resources.

Notes:
1. The right side column contains GTP/GTX Quads that displace ten block RAM blocks in that column per GTP/GTX Quad.
2. The column containing Gen1/Gen2 interface blocks for PCI Express® displaces five block RAM blocks per interface block for
PCI Express. Block RAM blocks cannot be cascaded across interface blocks for PCI Express.
3. The four center block RAM columns contain GTP Quads that displace ten block RAM blocks in those columns per GTP Quad.
4. The total block RAM block count is limited by software.
5. The block RAM column on the left side of the device has two less block RAM blocks per super logic region (SLR).
6. There are thirty 36 Kb block RAM blocks per column in each SLR.
7. The column containing Gen3 interface blocks for PCI Express displaces ten block RAM blocks per interface block for PCI Express.
Block RAM blocks cannot be cascaded across interface blocks for PCI Express.
