The core specifications of SK Hynix’s H5AN4G8NBJR-VKC form the foundation of its performance. The following are the key technical indicators for this memory chip, explained in detail in light of industry standards and practical application requirements:

1. Storage Capacity and Organisation Structure

The nominal storage capacity of the H5AN4G8NBJR-VKC memory chip is 4 Gb (gigabits), which converts to 512 MB in the commonly used byte unit. It employs a well-designed storage organisation structure that balances data read/write efficiency with chip integration. In terms of memory architecture, it utilises a 256M × 16 organisation, where the row address is 256M and the column address is 16 bits. This architecture effectively enhances data transfer bandwidth, reduces latency during data read and write operations, and is compatible with the data transfer mechanism of DDR4 synchronous DRAM, ensuring that data access proceeds efficiently and in an orderly manner in multi-tasking scenarios.

2. Operating Frequency and Data Rate

As a DDR4 synchronous DRAM chip, the H5AN4G8NBJR-VKC supports mainstream operating frequencies in accordance with the DDR4 standard, with a core data rate of up to 2400 MT/s (megatransfers per second). It is also compatible with lower frequency specifications such as 2133 MT/s, allowing for flexible adaptation to the motherboard support capabilities and application requirements of different devices. The synchronous DRAM design enables it to remain synchronised with the device’s system clock, ensuring that data read and write operations are precisely aligned with the clock signal. This effectively reduces timing errors in data transmission, enhancing the accuracy and stability of data transfer. In practical applications, this frequency meets the memory bandwidth requirements for scenarios such as everyday office work, entertainment and embedded control, ensuring smooth and lag-free device operation.

3. Operating Voltage and Power Consumption

Compared to DDR3 memory, a major advantage of DDR4 memory is its low power consumption. The H5AN4G8NBJR-VKC fully capitalises on this advantage, with a standard operating voltage of just 1.2V—significantly lower than the 1.5V of DDR3—effectively reducing the memory module’s power consumption and heat generation. Furthermore, this memory chip supports an energy-saving mode which automatically reduces power consumption when the device is under light load, thereby further extending battery life. It is particularly well-suited to products with stringent power consumption and battery life requirements, such as laptops, tablets and portable embedded devices.
