In the same announcement, they showcased the JMF810, a PCIe Gen II 2-lane controller, and the JMF811, a PCIe Gen II 4-lane SSD controller. Both are 4-channel SATA SSD controllers capable of supporting up to 512 GB of storage capacity. In June 2014, JMicron announced the JMF670 and JMF670H. Analysis in 2013 reveals that SSD controller technology and high-speed transmission interface IC accounts for 29% and 67% of JMicron's sales, respectively.

Shortly thereafter, in 2013, the JMF667 series was released as a 256 GB capacity, 512 MB DDR3 external cache SSD controller. In late 2011, the JMF661 was released as a third generation JMicron SSD controller, and it was shown to be an effective entry-level product. 2011 is characterized by JMicron winning orders from Western Digital and Samsung Electronics for JMicron's USB 3.0 HDD controller, with net sales projected to grow 10%. Īfter developing its own physical layer and high speed technology over the preceding years because of flat growth in the long term, JMicron diversifies from the base notebook and motherboard controller business.

In 2010 stolen private keys certificates were used for digitally sign rootkit drivers in Stuxnet virus. Also in 2010, a Gartner tandem research report reveals JMicron to be first in interface controller chip market share. In October 2010, JMicron was scheduled to list on the Taiwanese Gre Tai Securities Market (GTSM). In particular, 2009 was a landmark year for JMicron, in that the company achieved the top ranking as a supplier for external HDD and SATA-PATA bridge controllers, shipping roughly 35 million and 15 million units, respectively. It saw popularity throughout 2010 in its use in a number of industry SSDs. Also included in the showcase is the JMB38x series, a PCIe to card reader & 1394 controller chip, the JMB211, a Gigabit Ethernet PHY controller chip, the JMB352, a high-speed USB & eSATA to 2-port SATA II external HDD controller chip, and the JMB325, a 1- to 5-port SATA II port multiplier with hardware RAID. This includes the JMB353, a hi-speed USB & 1394a to SATA II external HDD controller chip this device is the first to feature an integrated 1394a PHY chip. 2008 to Present Īlso in 2008, JMicron showcases a number of peripheral products. Unfortunately the SSD controller did not have any support for DRAM cache, and with the NAND technology available at the time this made random writes very slow (the JMF602B improved this only slightly). JMicron was one of the first companies to provide an SSD controller chip to these companies, allowing them to produce reasonably priced SSDs.
JMicron's SSD controller is widely adopted by many SSD manufacturers such ASUS, Corsair, OCZ, and Transcend.
JMicron began developing SSD technology in 2006, launching their first generation SSD controller, the JMF601A/602A, towards the end of 2007. In 2002, the company began development of their USB 2.0 to SATA bridge controller technology. The company also operates an advanced R&D center based out of Irvine, California, United States. The company was founded in September 2001 and its headquarters is in Hsinchu, Taiwan.
