Posedge Inc. rolls NVM Express compliant Flash Controller IP Core.

While Flash-memory-based solid-state disks (SSDs) provide faster random access and data transfer rates than mechanical drives, typically the host interface to SSDs remains a performance bottleneck. An emerging standard called NVMe (Non-Volatile Memory express), promises to solve the interface bottleneck. Posedge's NVM Express defines an optimised register interface; command set that is scalable for the future and avoids burdening the device with legacy support requirements while sustaining performance in PCIe SSD applications, according to the company.

With the hardware and software interface standardisation Posedge NVMe compliant Flash Controller (FC) IP Core is said to provide a highly customisable interface, enhanced storage performance, reduced cost and unmatched flexibility. The NVMe FC supports multiple Flash devices (up to 16 devices) using single or multiple Flash Controller state machines. It is a part of Posedge's complete memory solution and is available in Posedge's Multifunction development platform.

The NVMe FC is integrated with other Posedge SSD/NAND Flash functional blocks to perform Error Correction, Bad Block management, File System support and Wear-Leveling. According to the company, the NVMe FC offers unmatched Data management flexibility, end-to-end integrity, interrupt coalescing, metadata handling, secure erase at a device level, and support of both SLC and MLC flash memories

According to the company, SoC designers can now confidently and easily integrate PE NVMe FC into their SoC's with high success rate. It has a low gate count and comes with World Class Customer support.
