Marvell has created the World’s First DRAM-less NVMe (Non-Volatile Memory Express) SSD controller for mobile computing solutions. The new controller only measures 8x8mm and by that allows for SSDs as small as M.2 2230 (22 x 30 mm). On top of that they come with industry-leading NANDEdge low-density parity-check (LDPC) technology and support for triple-level cell (TLC) and 3D NAND. Marvell’s 88NV1140 and 88NV1120 enable small form factor SSD solutions with unparalleled performance for integration into low-z-height tablets, Chrome devices and the upcoming wave of new 2-in-1 hybrid and detachable mobile PC platforms.
The controller works with both SATA and PCIe SSDs with the same firmware, allowing for easier integration and maintenance. It’s also best-in-class on active power consumption and supports the newest PCIe L1.2 and DevSleep functions. In addition, Marvell’s NANDEdge LDPC technology can support 15/16nm TLC and 3D NAND, resulting in low enabling cost of TLC and 3D NAND. The NVMe design has passed in-house SSD validation and third-party operating system and platform compatibility testing.
Key features of Marvell’s new 88NV1140 and 88NV1120 include:
88NV1140 and 88NV1120 both share:
- Powerful Dual core Cortex R5 CPU’s
- Embedded SRAM with hardware accelerators to optimize IOPS performance
- ONFI3 and Toggle2 NAND support
- NANDEdge error-correction: 15nm TLC and 3D NAND support using LDPC technology to boost endurance and reliability
- BGA SSD and M.2/2.5 slim form factor support with thermal optimization and small package size
- 28nm low power CMOS process
88NV1140:
- AHCI and NVMe support over PCIe Gen3x1
- Fully hardware automated NVMe 1.1b support
- Low power management (L1.2) design
88NV1120:
- SATA 6Gb/s support
- SATA DevSlp support
