AGIGARAM® DDR4 NVDIMM-N Memory Controller
The innovative ASIC targets JEDEC-standard NVDIMM-N products enabling significantly lower cost and power versus existing solutions, while offering advanced features such as encryption. During backup and restore operations, the controller manages the transfer of critical data between the on-board DRAM and NAND Flash. The highly configurable memory controller supports a number of memory vendors and specifications, allowing considerable flexibility for customers and partners.
Key features offered by the controller include:
- Integrated DDR4 DRAM Controller: supports multiple DRAM configurations, including single-rank, dual-rank, 3DS and integrated mux devices
- Integrated NAND Flash Controller: advanced ECC engine with support for up to 4-channels of ONFI 4.0 or Toggle 3.0
- High-Speed DMA: supports up to 1.2GB/s transfer rates enabling 30 second backup time for a 32GB NVDIMM-N, over 3 times faster than existing solutions
- AES256 Encryption: optional feature for secure backup
The AGIGARAM DDR4 Controller can significantly lower the total solution cost of NVDIMM-N products by eliminating the need for complex FPGAs and/or managed NAND/SSD controllers, while also shrinking the size of the energy source required to perform a backup operation. And with support for DRAM with integrated muxes, this helps to reduce cost and board space, while enhancing signal integrity and, most importantly, system performance. This all culminates in a more attractive NVDIMM-N solution for mainstream adoption by driving down the cost per IOPs.
