GENERAL DESCRIPTION
The IS29GL256 offers a fast page access time of 25ns with a corresponding random access time as
fast as 70ns. It features a Write Buffer that allows a maximum of 256 words/512 bytes to be
programmed in one operation, resulting in faster effective programming time than standard
programming algorithms. This makes the device ideal for today’s embedded applications that require
higher density, better performance and lower power consumption.
