IDT Intros Worlds First NV-DRAM PCIe v3 Controller


IDT is an American semiconductor company that’s more than 30 years old. While relatively less known to the usual PC user, it has once competed with AMD, Cyrix, Nat Semi and Intel for the desktop computer market.

Recently, IDT has impressively charged the enterprise SSD market with a powerful 32-channel NAND flash controller.

Considering that now they’ve just bought PLX, the maker of the famous PCIe bridge chips on AMD’s dual GPU cards, we can see that the company has apparently integrated the two concepts into a single chip.

The IDT 89HF08P08AG3 NV-DRAM controller comes with support for 32 GB of DDR3 SDRAM and 8 channels of NAND flash, with a PCIe x8 Gen 3 host interface.

This basically combines a PCIe v3 bridge with an SSD controller and a DDR3 memory controller into the same chip.

The NV-DRAM concept allows the system to use a large DDR-DRAM memory space to benefit from the impressive speed and minuscule access time, but will automatically backup all the data in the DRAM when a shutdown event is detected.

The controller supports different types of NAND and DDR3 memory with frequencies between 800 MHz and 1600 MHz.

One impressive thing we’ve noticed is the relative fast transfer speed rated by IDT for the cards powered by the new 89HF08P08AG3 NV-DRAM controller.

The card writes data directly into DDR3 DRAM at speeds of up to 3 GB/s and backups data with a write bandwidth of up to 1 GB/s when eight NAND flash channels and eight targets per channel are used.

All in all, it seem like IDT is very serious about the high-end enterprise storage market.
