Products and Services

Four new members have been introduced to the ComboMemory product family. The product family is comprised of 16 Mbit flash memory and 2 Mbit or 4 Mbit static random-access memory (SRAM). The new devices, while incorporating a dual-bank flash memory architecture, allow for concurrent operations between the two internal flash memory banks and the SRAM. Housed in a small, 8 mm x 10 mm Ball Grid Array (BGA) package with stacked-die technology, the new devices are ideal for mobile wireless communications applications such as Bluetooth- and WAP-enabled mobile phones and Internet-based PDAs. The new devices use the company's proprietary, high-performance CMOS SuperFlash technology combined with low-power SRAM process.

A distinguishing feature of the devices is that data can be read from either bank while an Erase or Program operation is in progress in the opposite bank. For added design flexibility, the flash memory is partitioned into 4 Mbit and 12 Mbit banks with top or bottom sector protection options for storing critical boot codes and configuration data. The devices are less susceptible to the effects of electromagnetic interference (EMI) and have a higher tolerance to the overall system's output of EMI. They offer a typical low standby current of only 6 microamperes, resulting in an extension in battery life.

The devices are designed to reduce space by replacing as many as three individual components (flash, SRAM and EEPROM) in traditional cellular phone applications. They incorporate the SoftPartition architecture, which allows system designers to seamlessly partition the data and program code into small, granular 1 KWord sectors.

Key Features:
• Dual-Bank Architecture for Concurrent Read and Write Operation
• Single 2.7-3.3V Read and Write Operation
• Dual-Bank Architecture for Concurrent Read and Write Operation
• 1 KWord sector erase capability
• Low Power Consumption
