Block RAM and Distributed RAM in Xilinx FPGA
- Xilinx FPGA Consist of 2 columns of memory called Block RAM or BRAM.
- It is a Dual port memory with separate Read/Write port.
- It can be configured as different data width 16Kx1, 8Kx8, 4Kx4 and so on.
- BRAM can be excellent for FIFO implementation.
- Multiple blocks can be cascaded to create still larger memory.
- The block RAM functions as dual or single-port memory.
- The maximum data path width of the block RAM is 18 bits.
- CLB LUT configurable as Distributed RAM
- A LUT equals 16×1 RAM
- Implements Single and DualPorts
- Cascade LUTs to increase RAM size
- Synchronous write and Synchronous/Asynchronous read
