What is the SDRAM and SSRAM used for in the PA-A3 and PA-A6 ATM port adapters and why is it important?
The synchronous dynamic random access memory (SDRAM) and the synchronous static random access memory (SSRAM) are used on the PA-A3 and PA-A6 ATM port adapter hardware to provide additional storage for the requirements of segmentation and reassembly (SAR) processing. This includes storage for the calendar scheduling table, and receive and transmit buffers.
