The H5AN4G6NBJR-VKKR is a 4Gb (Gigabit) DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random-Access Memory) chip manufactured by Hynix Semiconductor (now SK Hynix). DDR4 SDRAM is a high-speed, high-bandwidth memory technology widely used in modern computer systems and other electronic devices for temporary storage of data and instructions. It offers significant performance improvements over previous generations of DDR memory.

Applications:

• Desktop and Laptop Computers
• Servers
• Workstations
• Graphics Cards
• Networking Equipment

Features:

• 4Gb Density: Provides a storage capacity of 4 Gigabits.
• DDR4 Architecture: Offers higher data transfer rates and lower power consumption compared to DDR3.
• Double Data Rate: Transfers data twice per clock cycle (on both the rising and falling edges).
• On-Die Termination (ODT): Improves signal integrity and reduces reflections.
• Write CRC (Cyclic Redundancy Check): Provides error detection for write operations.
• Programmable CAS Latency (CL), Write Latency (WL), and Burst Length (BL): Allows for flexible configuration to optimize performance.
• Lead-Free and RoHS Compliant: Environmentally friendly.

Benefits:

• Increased Bandwidth: DDR4 offers significantly higher bandwidth compared to DDR3, resulting in improved system performance.
• Lower Power Consumption: DDR4 operates at a lower voltage than DDR3, reducing power consumption and heat generation.
• Higher Capacity: Enables larger memory capacities for demanding applications.
• Improved Reliability: Features like Write CRC enhance data integrity and reliability.

Additional Details:

The H5AN4G6NBJR-VKKR operates at a specific clock frequency and voltage, as determined by its speed grade and DDR4 standard specifications. The 'VKKR' suffix likely denotes specific performance characteristics or packaging details. It is packaged in a standard FBGA (Fine-Pitch Ball Grid Array) for surface mounting. DDR4 memory modules typically consist of multiple DDR4 chips mounted on a printed circuit board. The performance of DDR4 memory is highly dependent on the system's memory controller and chipset.
