Additional Details

The W9864G6GH-6 DDR2 SDRAM leverages a double data rate architecture, allowing data to be transferred on both the rising and falling edges of the clock signal. This effectively doubles the data transfer rate compared to single data rate (SDR) SDRAM. The inclusion of On-Die Termination (ODT) minimizes signal reflections and enhances signal integrity, especially crucial at higher operating frequencies. Programmable burst length options offer flexibility in tailoring memory access to specific application requirements. The self-refresh mode minimizes power consumption during idle periods. The '-6' likely indicates a particular speed grade or set of timing parameters within the product series.
