Greenliant Systems is an American manufacturer of NAND flash memory-based solid state storage and controller semiconductors for embedded systems and datacenter products. Greenliant is headquartered in Santa Clara, California, with offices in North America, Europe and Asia.[1]

Affiliations include JEDEC, NVM Express, PCI-SIG, SATA-IO, and the Storage Networking Industry Association.[2]


Silicon Storage Technology (SST) developed NANDrive technology which was recognized by trade publications in 2008 and 2009.[3][4] In April 2010, Microchip Technology acquired SST, while SST's founder and CEO Bing Yeh founded Greenliant along with other former SST executives.[5] In May 2010, Greenliant acquired NANDrive technology and other assets from Microchip for an estimated $23.6 million.[6][7][8]

The Greenliant logo symbolizes a multi-chip module with an energy-efficient core and the name represents green and reliable.[9]

In November 2010, Greenliant began sampling its Serial ATA interface NANDrive GLS85LS products, which had up to 64GB capacity in a 14mm x 24mm x 1.95mm, 145 BGA (ball grid array), 1mm ball pitch package.[10][11][12]

In June 2012, Greenliant began sampling its embedded MultiMediaCard interface NANDrive GLS85VM products, which operate at industrial temperatures between -40 and +85 degrees, and are offered in a 14mm x 18mm x 1.40mm, 100-ball, 1mm ball pitch package.[13][14][15]


NAND flash memory controller products manage the inherent deficiencies of NAND flash, providing a simpler interface to a computer system.[16]


A large-capacity storage solution, G-card combines Greenliant's advanced controller and an array of small form factor NANDrive solid state storage devices, in a standard PCIe add-in card format.


NANDrive embedded solid-state drives (SSDs) consist of an integrated controller and NAND flash die in a small multi-chip package. GLS85 devices have the same size across all capacities in each family, are backwards compatible and designed for commercial and industrial grade temperatures.[17][18]

NANDrive devices have content protection zones and users can select areas of the storage to protect with fast erase.[19]

ArmourDrive mSATA[edit]

ArmourDrive mSATA solid-state drives (SSDs), are based on SATA NANDrive, using Greenliant’s internally developed NAND flash memory controller. Dedicated power failure detection and backup power circuitry are built-in to prevent data integrity issues due to sudden power interruptions.[20][21]

Concurrent SuperFlash[edit]

Specialty flash memory includes the Concurrent SuperFlash (CSF), Many-Time Programmable and Small-Sector Flash (SSF) families. Available in commercial, extended and industrial grade temperatures, these products are marketed for space and power-constrained code storage applications.[22]
