Additional Details

The W9864G6EH-6 DDR2 SDRAM utilizes a double data rate architecture, enabling data transfer on both the rising and falling edges of the clock signal. This significantly increases the data transfer rate compared to single data rate (SDR) SDRAM. The On-Die Termination (ODT) feature reduces signal reflections and improves signal integrity, especially at higher frequencies. The programmable burst length options allow the user to fine-tune the memory access for their specific application. The device also supports self-refresh mode, which minimizes power consumption during idle periods. The '-6' likely refers to a specific speed grade or timing parameter within the DDR2 SDRAM family.
