RE: HP-48 FRAM Cards
(07-23-2016 12:58 AM)JDW Wrote: The data shows FRAM to have greater endurance than Flash, and most computers use SSDs now. So in effect, you're safer using FRAM in a 48GX than a computer is using its SSD! How is that a knock against FRAM in a 48GX?The point is that SSDs and flash cards are used for data storage (replacing hard disks etc.), not to replace a computer's RAM (SRAM or DRAM), where many orders more read-write-cycles will occur. As I wrote already, FRAM is a great idea for cards used in slot 2 (where the memory is used for storage). However, I consider it pointless to expand the calculator's RAM using a 128 KB FRAM card in slot 1, not only because of the somewhat limited life-time of the FRAM card in this configuration, but also because the other 128KB half of the calculator's memory remains SRAM - that is, the calculator would still loose its memory contents, when the batteries are exhausted. This drawback could be eliminated only by replacing the internal memory by FRAM as well... Greetings, Matthias -- "Programs are poems for computers." |
