AMD Announces New Flash Family for High Performance Applications; Optimized for Page or Burst Mode Operation.SUNNYVALE, Calif.--(BUSINESS WIRE)--Sept. 8, 1998--AMD today announced a new family of 16-Mbit flash memory devices featuring data access speeds as fast as 18 nanoseconds. These devices are targeted at applications with the highest system performance requirements. The family contains devices that are optimized for either page or burst mode operation. "This family offers simple and economical flash memory solutions for high performance embedded systems Embedded systems Computer systems that cannot be programmed by the user because they are preprogrammed for a specific task and are buried within the equipment they serve. ," said Walid Maghribi, group vice president of AMD's Memory Group. "By offering a family of devices, AMD (Advanced Micro Devices, Inc., Sunnyvale, CA, www.amd.com) A major manufacturer of semiconductor devices including x86-compatible CPUs, embedded processors, flash memories, programmable logic devices and networking chips. allows designers to choose a flash memory solution that can be implemented with the most popular microcontrollers with little or no glue logic A simple logic circuit that is used to connect complex logic circuits together. For example, an ASIC chip may contain large functions, such as a microprocessor, memory block or communications block, which are tied together via small amounts of glue logic. ." Burst Mode Flash Three members of the family operate in synchronous burst mode with automatic wrap-around. Each provides a different burst read operation tailored to meet the requirements of specific microprocessors. Initial data access requires 65 nanoseconds. Subsequent data can be accessed as fast as 18 nanoseconds. The three modes of operation are: Modulo A mathematical operation (modulus arithmetic) in which the result is the remainder of a division. Also known as the "remainder operator," it is used to solve a variety of problems. For example, the following code in the C language determines if a number is odd or even. Burst: Four-word sequential burst. Interleaved Burst: Four-word interleaved burst. Linear Burst: 32-word sequential burst. Page Mode Flash The AMD page mode device consists of eight word pages. After an initial data access of 65 nanoseconds, data can be read asynchronously from any other location within the page as fast as 25 nanoseconds. Using page mode flash memories, designers can eliminate shadow RAM or bank interleaving interleaving - sector interleave , resulting in lower system cost. Applications Target markets for burst mode flash memory include automotive, telecom, internetworking, and any other high performance systems. Applications for page mode flash include printers, network interface cards and other high performance systems. Features -- High Performance The burst mode devices provide an initial access time of 65 nanoseconds and sequential burst accesses of 18 nanoseconds. The page mode device provides an initial access of 65 nanoseconds and fast page accesses of 25 nanoseconds. -- Operating range of 2.7-3.6-Volt -- 5.0-Volt tolerant inputs and outputs Simplifies operation in 5.0-Volt systems without requiring a separate 5.0- Volt I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output source. -- Interfaces directly with most microprocessors with little or no glue logic. -- Zero-Power Operation During normal operation, most portable systems have many inactive periods. AMD's advanced power-management system automatically puts the device into sleep mode during these inactive periods, consuming virtually zero power. There is no latency/wake-up time when the system subsequently accesses the device. -- Software Compatible The software command set is compatible with the command sets of the other members of AMD's single power supply 5.0-volt-only and 3.0-volt-only flash families, making its command sequences JEDEC The division of the Electronic Industries Alliance (EIA) that deals with semiconductor standards (officially, the JEDEC Solid State Technology Association of EIA). JEDEC was formed in 1958 when the Joint Electron Tube Engineering Council (JETEC) split into two Joint Electron Device compatible. -- Packaging The page mode device is available in a 44-pin PSOP PSOP Plastic Small Outline Package PSOP Personal Stock Option Plan PSOP Power Small Outline Package . The burst mode devices are initially available in a small form factor 56-pin SSOP SSOP Shrink Small Outline Package SSOP Sanitation Standard Operating Procedures (USDA) SSOP Sanitary Standard Operating Procedures SSOP Sharescan-Open Platform (Ecopy) SSOP Site Security Operational Procedures . They will also be packaged in a 56-pin TSOP (Thin Small Outline Package) A very thin, plastic, rectangular surface mount chip package with gull-wing pins on its two short sides. TSOPs are about a third as thick as SOJ chips. See gull-wing lead, SOP, SOJ and chip package. . Availability Samples of the Am29PL160, the page mode device, are available now. All three burst mode devices will be available for sampling in Q3 and Q4 of this year. The price for either the page or burst mode part is $9.25 in 10,000-piece quantities.
