AMD announces new multi-chip memory packages

Advanced Micro Devices (AMD) launched a family of multi-chip package (MCP) flash memory and SRAM (static random access memory) packages aimed at mobile phone manufacturers, the company announced Tuesday.

The new products allow companies to select any combination of 16M, 32M or 64M bytes of flash with 2M, 4M or 8M of SRAM in a single footprint.

In a mobile phone, the flash memory acts like a hard drive, so elements like the operating system are on flash, said Kevin Plouse, vice president of Technical Marketing and Business Development for AMD's Memory Group. But one thing flash doesn't do is write fast, he said.

For example, to store a phone number in a phone, the number would be written into SRAM as the user entered it on the keypad, he said. Then when the user saved the number, it would be written slowly into flash.

Flash storage also plays a part in games, WAP (Wireless Application Protocol) browsers and anything else on the phone, he said. "Flash enables the mobile phone to evolve from a simple communications device to a mobile information terminal," Plouse said.

All of AMDs MCP products incorporate SRAM and flash in one package, saving board space and increasing performance, so portable device makers can create smaller, faster products, AMD said. Since all products offer the same footprint, customers can design a single board, and still offer multiple versions of their products, the company said in a statement.

The Am41DL16304 with 16M bytes of Flash and 4M bytes of SRAM is available now and is priced at US$9. The Am41DL32304 with 32M bytes of Flash and 4M bytes of SRAM is available now and is priced at $12. The Am41DL32308 with 32M bytes of flash and 8M bytes of SRAM is available now and is priced at $14.50. All prices are in 10,000 piece quantities, a standard measurement for chip sales.

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
