Abstract
The invention relates to a buffer memory, method and a buffer controller for queue management usable in an ATM switch. An object of the invention is to achieve a high frequency throughput of data cells in the buffer memory. This object is achieved by using a buffer memory which is organized as 256*(424+8) SRAM-cells. The memory is used for holding ten queues, one for each incoming channel and two free-queues containing idle cells.
