data remanence - speed (or lack thereof...)

Unread post by ledan »

Its sort of modx related (as i'm currently loading up a few banks that i got recently into my modx6) to the sub-forum so please forgive me if this is too generic (but it is modx related ;))

I'm reflectig on the rather poor write-speed of the build in 1gb of flash memory that this unit has. During the history of about 20 years or so, i have had other instrument where either the sequencer OR non-volatile sample storage have been based on this type of memory (i guess its related to CMOS technology in the end). I haven't really seen any speed boost when using this type of memory during all this time. So herein lies my question:

With all progress as of lately (20 years until now) what is really blocking this tech. from achieving decent speeds? What other technology is out there that could essentially replace SRAM but act similarly (if at all possible) and if such a thing exists, what stops Yamaha and others from using it?


(yes, I'm impatiently waiting for the bank to flash here... :mrgreen: )

AFAIR for the MODX/Montage the limiting factor is not the memory speed but the internal architecture that needs operations that involve data transfer from USB to flash to go from the main CPU (with a rather slow bus) through the SWPB70 chips (that have fast access to the flash) to get there.
