Integrated Device Technology, Inc. (IDT) announced a new flash memory expander that allows designers to develop high-capacity, high-performance solid-state drives (SSDs) for data center and enterprise applications. The MX0141K expander enables SSDs using existing ONFI 4.1 components to improve overall signal integrity between the controller and NAND flash and allows a larger array of NAND devices to operate at maximum NV-DDR3 interface speeds.
To achieve high-capacity SSD requirements, designers are required to place up to 16 die per channel or more on a controller. As the NAND performance requirements increase to 1200 MT/s, the capacitive loading on the bus introduces signal integrity issues and higher speeds cannot be achieved. The IDT 1:4 expander isolates NAND die on the bus to enable the highest speed operation and is the first to support port speeds up to 1600 MT/s in SSD applications.
IDT has collaborated with Marvell to develop an innovative SSD reference design featuring the MX0141K and Marvell’s 88SS1098 controller, creating a U.2 solution to maximize capacity and performance without expanding design footprint. The 88SS1098 controller enables high-performance and high-capacity SSDs to meet the demands of challenging workloads in enterprise and data center environments.
Housed in a low-power, compact 4 mm x 11 mm 126-FCCSP package, the MX0141K is sampling now to select customers. Requests for datasheets and samples can be submitted at idt.com/MX0141K.
