Numonyx introduced the its 65-nm multiple I/O serial flash memory product line, called the Forte N25Q serial flash family. The serial peripheral interface (SPI) flash memory delivers a broad spectrum of performance features and density ranges. This introduction adds two new products at 128 Mbits in 3- and 1.8-V versions manufactured on 65-nm technology.
The product extends and improves the design flexibility and usability of serial flash memory by incorporating a non-volatile configuration register. This feature optimizes the device configuration by allowing multiple parameter options that are best suited for the application and maintains the settings after the power on and off cycle. This non-volatile capability enhances the flexibility of execute-in-place (XIP) memory systems by eliminating the need to reset the device after each power cycle, and improves performance by reducing the number of clock cycles. Designing with the Forte N25Q family could also potentially reduce the DRAM in the system by executing the code directly from the flash device, saving cost and board space for customers.
The N25Q serial flash memory supports multiple I/O SPI protocols (single, dual, and quad) on the same device, which increases flexibility. Read and write speeds have been improved over the entire supply voltage range, improving clock speeds from 75 to 108 MHz and up to four times, or 432 MHz, in the quad I/O mode. At both 3 and 1.8 V, the Forte N25Q is well-suited for a range of applications, including battery-operated devices, such as handheld or consumer electronics.
Production quantities of the 128 Mbit part in both 3 and 1.8 V are available now.
