Guys, I ran into these memory chips: KM41256AJ-15 - 256K X 1 Bit Dynamic RAM with Page / Nibble Mode - semiconductor

Anyone knows what they are? Are used in any pedal and are they worth anything?

Hi, thats 256kBit dynamic RAM 
The last computers using it schould be at least 10 years old.
I doubt that they have ever been used in any Guitar gear.

Sorry.

Thanks!

I don't remember which chips were used, but some of the Digitech pedals (XP series) used DRAM I believe.
