Advanced eMMC with a smaller size and reduced power consumption

Smart wear, or wearable intelligence, refers to the ability of humans to better comprehend themselves and external information via physical gadgets. Sports fitness and healthcare are the most popular domains for sensing self-information, with wearable motion sensors, smart watches with health data management functions, and so on. Its application fields for the perception of external information are relatively broad, ranging from leisure and entertainment to information exchange and industrial applications, such as VR game suits with gamepads and visual capture modules, smart glasses for visual and audio interaction, and winter sports.

As the user population grows, product shapes are gradually diversifying, and product characteristics are fast evolving towards intelligence and downsizing. Memory chips with enhanced process technology, reduced chip size, and lower power consumption are therefore absolutely essential for wearable devices.

An embedded MultiMediaCard (eMMC) is a tiny storage device composed of NAND flash memory and a straightforward storage controller. The technology is designed for use in mobile devices such as cell phones and, more recently, sensors linked to the Internet of Things (IoT). The flash memory and controller are both housed on a single integrated circuit (IC) that is permanently implanted in a device.

An eMMC serves as the primary storage device for portable devices such as mobile phones and tablets, which can be supplemented by a detachable Secure Digital card or microSD multimedia card.

Subsize eMMC is basically an eMMC device that considers JEDEC pin definitions. It is smaller in size and takes up less room. It is appropriate for applications with limited space, such as smart watches and TWS.

A flash memory controller and integrated non-volatile memory system known subsize eMMC makes application interface design simpler and frees the host CPU from low-level flash memory management. The non-volatile memory interface design and qualification process is made easier for product developers, which reduces time-to-market and makes it easier to accommodate upcoming flash device options. Subsize eMMC is a practical, affordable memory option for mobile and other goods with limited space because to its small BGA chip sizes and low power consumption.

High capacity in a tiny package

Capacities range from 4GB to 256GB and are graded according to the application (i.e. consumer & industrial) The most common eMMC sizes are 32GB and 64GB, which employ mostly SLC or 3D MLC NAND flash and are suited for demanding applications. Given its compact size, eMMC can handle unusually huge volumes of data in such a small footprint.

Interface design

Subsize eMMC streamlines the interface design and qualification process for developers, resulting in a shorter time to market and easier support for future flash device offerings.

Performance that is unbeatable for mobile storage

Subsize eMMC the undisputed option for flash storage to create thin mobile designs because of its better power economy and significantly rapid performance.

Consistently the best speed

Subsize eMMC delivers outstanding performance at a quicker processing speed for today's smaller, sleeker smartphones and tablets. It is cutting edge and competitive. Heavy workloads are readily handled by subsize eMMC, which achieves maximum sequential Read/Write rates of 330MB/s and 200MB/s (based on 64 GB).

Effectiveness at low power

84 percent reduced energy use longer application life for mobile devices.

Subsize eMMC, which was created to improve the mobile user experience, exhibits great power management and remarkable performance with low power consumption of just 0.5 watts, or around 84 percent less than the lowest-consuming SSD.

Large selection, rapid response

Subsize eMMC, ranging from 4GB to 256GB, completely meets industry standards for tiny package sizes and fast interfaces. With an established supply chain, subsize eMMC also delivers reassuringly steady product management for fast-moving mobile markets, allowing for quick customer reactions.

Affordable Internal Storage Method

Because it is less expensive than other smaller internal storage options like Universal Flash Storage (UFS) and NVMe-based solid-state storage, most makers of low-cost laptops and devices like smartphones and tablets prefer utilizing an subsize eMMC. The lower manufacturing costs and lower selling prices made possible by this storage technology allow firms to cut their costs.

Compact Size Equals Minimal Footprint

An Embedded MultiMediaCard's physical dimensions range from 11 x 10 x 0.8 mm to 11.5 x 13 x 1.2 mm. Be aware that an subsize eMMC is 10 to 20 times smaller than a solid-state drive based on PCIe. Undoubtedly, the best internal storage option for portable devices is a large storage capacity. It is the perfect internal storage option for compact laptops and netbooks as well as smart gadgets because to its tiny footprint and high storage capacity.

Outlook

FORESEE's embedded storage solutions concentrate on both consumer electronics and the service sector. It has also introduced eMMC, eMCP, UFS, LPDDR, and ePOP products in addition to subsize eMMC, all of which are extensively utilised in a variety of industries, including smartphones, tablets, set-top boxes, digital TVs, in-vehicle devices, and IOT devices.
