moviNAND™

what is moviNAND?
moviNAND = High-density MLC NAND Flash & MMC controller

moviNAND

features & benefits
easy to use
  • Simple read/write memory using industry-standard MMC protocol 4.2 interface
  • No need to develop firmware for MMC controller
provides cost-effective solution
  • Faster product development and time to market
  • Common solution for embedded and external flash memory
  • Low-cost embedded solution with MLC NAND
  • Performance increase costs less
    - 4 stacked raw NAND - must increase performance of all NAND (4 times overhead)
    - 4 stacked moviNAND - increase performance of just one MMC controller
  • Can be used with low-cost legacy chipsets
    - Solutions for legacy chipset supporting only SLC interface with MMC interface
  • JEDEC standardization in process
NAND technology changes invisible to the host
  • The trend of NAND standardization (e.g., ONFI) does not mean raw NAND will not change
  • Variation of NAND flash feature NAND block sizes, page sizes, planes, new features, MLC vs. SLC, wear leveling and ECC requirements

moviNAND (eMMC) is an embedded storage solution with an MMC interface, flash memory and controller, all in a small BGA package. It is based upon the industry-standard MMC System Specification v4.2 and JEDEC BGA packaging standards. With interface speeds of up to 52 MB per second, moviNAND provides fast scalable performance. It supports x1, x4 or x8 bus width and allows for an interface voltage of either 1.8v or 3.3v.

moviNAND provides a flexible, industry-standard architecture that simplifies mass storage designs for portable consumer electronics products. With moviNAND, a host system can now gain access to all major classes of mass-storage memory subsystems, including embedded memory (moviNAND), memory cards or even hard disk drives (via ATA-on-MMC specification) with one common MMC Interface Protocol Bus.

MoviNAND architecture

The standardized moviNAND protocol interface offers designers high performance and makes technology complexity -- such as NAND Flash functional differences among suppliers -- invisible to the host. This differs from the conventional architecture, where a host system must contend with generational process geometry shrinks and technical complexities such as Multi-Level Cell (MLC) technology while supporting the company-specific functions of individual flash memory suppliers to achieve the necessary performance.

The benefits of moviNAND to host manufacturers are a simpler product design and qualification process and shorter time to market overall.

dual power supply
  • 3.0V (2.7V ~ 3.3V) for MLC NAND Flash
  • 1.8V/3.0V for I/O
MMC4.1 or 4.2 interface
  • x1, x4, x8 bus & 26MHz, 52MHz
moviNAND reduces TAT
typical TAT with NAND
  • Changes in Chipset/OS/NAND require change in FTL
  • Change in FTL requires NAND-level testing
