An IPv6 Refresher--Part II Design How-To 7/28/2006 Post a comment Excerpted from Deploying IPv6 Networks, Chapter 2--An IPv6 Refresher, Part II concentrates on special use addresses, IPv6 Anycast Addresses, Multicast Addresses, IPv6 and Layer 2 Addressing and IPv6 Addressing Architecture at a Glance.
An IPv6 Refresher--Part I Design How-To 7/24/2006 Post a comment Excerpted from Deploying IPv6 Networks, Chapter 2--An IPv6 Refresher, this comprehensive series covers the concepts fundamental to undertsanding IPv6, including: the new addressing architecture, new header format and structure, enhanced functions of ICMP, and Layer 2 address-resolution mechanisms.
Amtech tag lets RFID ride the rails Teardown 7/24/2006 Post a comment
North of Austin is a piece of Old Texas where two railroad lines and a 120-year-old lime factory converge. During a recent train-spotting stop, I found a curious little box trackside and recognized it as an asset-tracking badge that had somehow gotten detached from a passing railcar. That meant electronics within--and a teardown waiting to happen.
4-Gbit NAND built at 65 nm Teardown 7/17/2006 Post a comment
Samsung has established the No. 1 market position in the top two semiconductor memory markets. But even as the memory leader, the company is not known for coasting. It continues to scale memory products aggressively into advanced geometries, a technique it used to achieve its current position. The latest example of Samsung's scaling efforts is the 4-Gbit NAND flash, the first standalone memory to be manufactured at the 65-
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
