eMMC-based storage solutions
eMMC is a type of Fusion Memory, and a standard for embedded memory devices that contain both data storage element (such as NAND flash memory) and controller for element integrated on the same silicon die. This results in several advantages, such as reduced development time and easier integration of the memory block in the overall system; ultimately leading to a much shorter time-to-market for the product. Samsung's eMMC solution consists of three components - the MMC (multimedia card) interface, the flash memory, and the flash memory controller. It is offered in the industry-standard BGA package.
is a new architecture of eMMC that is presently under development. It eliminates the need to develop interface software for all types of NAND memory by integrating the embedded controller onto the memory chip and providing an easy-to-use memory solutions package for high-speed data transmissions by devices such as mobile phones. moviMCP also eliminates the need for a memory expansion slot by stacking several memory functions vertically, resulting in a very small footprint for the end memory devices. As an example, moviMCP can be deployed to store the code for an application in the SLC NAND/NOR and DRAM memory, whereas the data can be stored in the eMMC memory in a device.
Key specifications of Samsung eMMC v4.41-based storage solutions are listed below:
- Densities: 2 GB to 64 GB
- Supported bus widths: x1, x4, or x8
- Supported interface voltages: 1.8 V or 3.3 V
Common digital still/video cameras require a microcontroller (MCU) for functions such as operating the flash and controlling the electrical motor that operates the optical zoom lens on the camera. The MCU typically operates under the control of a higher and more powerful processor (most commonly, a Digital Signal Processor (DSP)).
Samsung comprises a large array of MCUs for deployment on a vast variety of applications. Starting from basic 4-bit MCUs, Samsung MCUs range right up to 32-bit ARM-based RISC MCUs with best-in-class quality of on-chip flash, SRAM, and inbuilt CAN interfaces. Samsung has an entire range of products based on the industry-standard ARM Cortex cores, which deliver exceptional computing power at significantly lower power consumption levels.
While low-end MCUs with 8-bit cores are used as general-purpose, low frequency controllers, mid-range and high-end cores are targeted at specific segments, such as high-speed, high performance, and low power applications. Samsung provides extensive software support, including a custom-designed C compiler for Samsung MCUs, to help accelerate software development for products on the platform.
Key specifications of Samsung controllers are listed below:
- On-chip memories: Up to 32 KB RAM and up to 1 MB ROM
