Description of eMMC 5.1
EMMC (Embedded Multimedia Card), as an embedded storage solution that integrates flash memory chips and controllers, has become a "storage necessity" in the consumer electronics field due to its high integration, low power consumption, low cost, and stable compatibility. In the two major scenarios of smart homes and multimedia playback boxes, it precisely matches the core storage requirements of devices, supporting stable operation of basic functions while balancing cost and experience.
Main Features of eMMC 5.1
Using high-quality wafers from Kaixia: Kaixia's high-quality wafers, such as 9T25 wafers, use the latest BiCS FLASH technology ™ The 3D TLC flash architecture integrates higher capacity storage units in a single chip through 112 layer vertical stacking technology.
Paired with SMI controller: The SMI controller is equipped with hardware level LDPC (Low Density Parity Check) algorithm, which can detect and correct burst errors of 12bit/1KB in real time, and control the uncorrectable bit error rate (UBER) below 1e-17, which is 100 times stricter than JEDEC standards, effectively ensuring the accuracy and integrity of data.
Rich capacity options: Provides a capacity range of 64G~256G, which can meet the different storage capacity requirements of various application scenarios such as mid to low end smartphones, tablets, and IoT devices.
Applications of eMMC 5.1
Smart home scenario: The core value of eMMC lies in "lightweight adaptation" and "stability and reliability". Smart home devices, such as smart speakers, smart cameras, smart central control screens, smart door locks, etc., generally pursue miniaturization design and rely heavily on low-power power supply (batteries or low-voltage power sources). The single-chip integrated design of eMMC (without the need for additional controllers) can greatly save internal space and adapt to compact circuit board layouts. At the same time, its low-power characteristics can extend device endurance (such as battery powered smart door locks) and reduce energy consumption during standby.
Multimedia playback boxes (such as network set-top boxes, 4K playback boxes, TV boxes, etc.): The core role of eMMC is to "support media experience" and "balance cost-effectiveness". The core functions of such devices are decoding and playing videos, loading applications, and running systems. EMMC requires storage of the device's operating system (such as Android TV system), video decoding driver, app store, and pre installed video apps (such as streaming platform clients and local playback software).
