GENERAL DESCRIPTION
The IS29GL256/128 offer a fast page access time of 20ns with a corresponding random access time as
fast as 70ns. It features a Write Buffer that allows a maximum of 32 words/64 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.
