eMMCmuisti

eMMCmuisti, which stands for Embedded MultiMediaCard, is a type of embedded storage solution commonly found in portable electronic devices. It is a standardized form of flash memory that integrates the flash memory chip and a simple controller onto a single integrated circuit package. This integration allows for a smaller physical footprint and reduced power consumption compared to traditional removable storage solutions like SD cards.

The MultiMediaCard (MMC) standard itself was developed to provide a low-cost, high-performance memory card solution. eMMC builds upon this by embedding the storage directly into the device's motherboard. This makes it a popular choice for smartphones, tablets, e-readers, and other compact consumer electronics where space and power efficiency are critical.

eMMC interfaces typically use a parallel bus, although newer versions support a high-speed serial interface. The integrated controller handles tasks such as error correction, wear leveling, and bad block management, simplifying the design for device manufacturers and improving the reliability and longevity of the storage. While eMMC offers a good balance of performance, cost, and size, it is generally slower than more advanced storage technologies like UFS (Universal Flash Storage) or NVMe SSDs, which are often found in higher-end devices.
