Best SKhynix eMMC Products Overview

Introduction to SKhynix eMMC Products

SKhynix eMMC products are widely used in consumer electronics that require high storage capacity. They are composed of an embedded storage solution with an MMC (Multimedia Card) interface, flash memory devices, and a main controller, all integrated into a small BGA package. These products offer fast and upgradeable performance, with an interface speed of up to 52MB per second. The interface voltage can be either 1.8V or 3.3V.

Key Components and Structure

SKhynix eMMC products are built by combining a NAND chip and a controller in a single package. This design enables the eMMC solution to minimize changes to the host due to NAND process variations. As a result, it simplifies both hardware and software design for customers. The built - in intelligent controller manages interface protocols, wear - leveling, bad block management, garbage collection, and ECC (Error - Correcting Code). It also protects data from the risk of loss caused by sudden host power - off.

Compatibility and Standards

SKhynix eMMC products are compatible with the international JEDEC standards. For example, some e - NAND products are compliant with the JEDEC standard eMMC5.1 specification. This compatibility ensures that these products can be easily integrated into various systems, providing a standardized and reliable storage solution for device manufacturers.

Performance Features

1. High - speed Interface Modes: Some SKhynix eMMC products support the HS400 signaling mode. Through a 200MHz DDR clock frequency, they can achieve a bus speed of 400MB/s. However, the HS400 mode only supports an 8 - bit bus width and a Vccq of 1.8V. The high - speed interface allows for quick data transfer, enhancing the overall performance of the device.
2. Storage Density and Sequential Read/Write Speeds: For instance, a 64GB (QDP) SKhynix EMMC may have a sequential write speed of 170MB/s and a sequential read speed of 280MB/s. These speeds are measured under specific conditions, such as with a device - level tool, an eMMC I/F speed of HS400, and a sequential chunk size of 512KB.

Power Consumption

1. Active Power Consumption: During operation, the power consumption of SKhynix eMMC products is affected by factors such as temperature and current consumption. At a temperature of 25°C, for a 64GB (QDP) eMMC, the average current consumption over a 100ms period and the peak current consumption over a 20us period are important parameters. With Vcc at 3.3V and Vccq at 1.8V, the device has specific power - consumption characteristics.
2. Low - Power Modes: SKhynix eMMC products also feature low - power modes, including idle and sleep modes. In the idle mode, the current consumption is relatively low, and in the CMD5 - triggered sleep mode, the NAND VCC power can be turned off while the CTRL VCCQ remains on, further reducing power consumption.

Data Security and Management Features

1. ECC and Wear - Leveling: The ECC function helps to detect and correct errors in data storage, ensuring data integrity. Wear - leveling technology evenly distributes write operations across the NAND flash memory, prolonging the lifespan of the storage device.
2. NAND Partitioning: SKhynix eMMC products support NAND partitioning, which allows customers to divide MLC and SLC NAND partitions. SLC can be used to store frequently accessed boot code, while MLC stores data. This not only reduces component costs but also saves space on the phone's circuit board.

Product Examples

1. H5AN8G6NAFR - UHC: This is a SKhynix eMMC storage product. It is available in the market with different pricing based on the quantity ordered. For example, it costs $15.00 per piece for orders of 10 pieces or more, $14.70 per piece for orders between 160 - 1599 pieces, and $12.00 per piece for orders of 1600 pieces or more.
2. H9HP52AECMMDAR eMCP 64GB EMMC(x8) 48GB: This product also showcases the performance and features of SKhynix eMMC, with specific density - related sequential read and write speeds and power - consumption characteristics as mentioned above.

In conclusion, SKhynix eMMC products offer a comprehensive set of features, including high - speed performance, low power consumption, data security, and ease of integration. These features make them an excellent choice for a wide range of consumer electronics applications, providing reliable and efficient storage solutions for modern devices.
