AMD introduces more secure Flash memory

Advanced Micro Devices (AMD) has introduced a 64M-bit Flash memory chip, the Am29PDL640G, which incorporates security features designed to protect smart phones and set-top boxes from attacks by hackers.

The Am29PDL640G is a 3.0-volt page-mode Flash chip that is equipped with several security features, including 64-bit password protection that prevents unauthorized users from making changes to memory and a persistent sector protection mode that offers a defense against viruses, AMD said in a statement. The chip also includes a 256-bit one-time-programmable space for an electronic serial number or other information, it said.

From a performance standpoint, the Am29PDL640G has an initial access time of 65 nanoseconds (ns) and a page access time of 25ns. It offers data throughput of up to 80M bytes per second, allowing applications to load quickly on a cell phone, AMD said.

The Am29PDL640G device is priced at US$9.75 each in quantities of 10,000.

It’s perfect for mobile workers. Just take it out — it’s small enough to sit anywhere — turn it on, load a sheet of paper, and start printing.
