Programming Time for Micron Memory Device
Today's Flash memories are divided into several sectors and usually require less complex programming algorithms. Being able to perform sector erase will save time by allowing one sector to be erased at a time. Flash erase cycles could be very long and the number of guaranteed erase / re-write cycles is usually limited. Erasing an entire sector just because one variable changed could be costly for today's project cycle. To avoid such dilemma, Xeltek has implemented Sector Erase capability to support
Micron N25Q devices.
Many serial Flash memory applications need users to quickly update BIOS partition with specific data and in those cases sector erase will be extremely helpful.Most programmers use bulk erase to erase device which introduces unnecessary delays. The SuperPro 7500 programmer provide the Sector Erase feature for N25Q008A, N25Q016A, N25Q032A, N25Q064A, N25Q128A, N25Q256A, N25Q512A and N25Q00A devices. Sector Erase could also be implemented on the ISP programmer, Superpro IS01 upon customer's request.
Specific sector numbers could be selected in the Device Configuration window of the software:
