The UltraRAM key features are:

  • 288K bits of storage in a single block.
  • Dual port, 32k x 9, 16k x 18, 8k x 36, and 4K x 72, single clock synchronous memory.
  • UltraRAM cascade for building larger blocks. UltraRAM has dedicated routing resources for appropriate inputs and outputs to cascade from lower UltraRAM to upper UltraRAM.
  • Error correction coding (ECC) on both ports with single bit error detection and correction and double bit error detection.
  • Sleep power saving features.
  • Automatic power savings through automatic invocation/release of the sleep mode in a chain of UltraRAM blocks.
  • Optional pipeline flip-flops on the inputs, outputs, and cascade paths.
  • Data out reset capability for outputs to be reset to all 0's.
  • Single port widths of x9, x18, x36, and x72.
  • Initialize to zeros or to user-defined values.
