Memblaze, China: Flash Solid State Disks

Solid-state disk design based on PCIe gains speed and performance with Xilinx 7 series devices.

Solid state disks (SSDs) based on PCI Express® are making a huge impact on the market. The industry-standard local bus offers higher performance and scalability than SATA. However, creating a PCIe-based SSD system using 19-nm flash has its share of challenges.

In the MemBlaze China design, the 7 series PCIe hard core implements the physical-to-TLP layer and allows the design to function as a high-performance PCIe endpoint with minimal latency. The new embedded MicroBlaze™ core with ARM® AXI4 interconnect removes the bottlenecks of the on-chip bus.

Xilinx Kintex-7 series FPGAs are ideally suited for 19-nm flash PCIe SSD designs. The hard PCIe core, the performance, capacity and low power make it the perfect chip for this market. With this device, our SSD throughput easily maintains 2 GBps for both writing and reading. The device allows us to bring a great value to our customers and gain a large margin for our 19-nm NAND flash system.
