Memory Structure - Yamaha PSR-9000 Owner's Manual

Memory Structure

The PSR-9000 features three different memory provisions for storing your original data: Flash ROM,
RAM, and Disk.
Flash ROM
The PSR-9000 includes special Flash ROM memory. Unlike conventional ROM, Flash ROM
can be overwritten — allowing you to store your own original data. The contents of Flash
ROM are maintained even when the power is turned off.
RAM
This is the conventional "internal" user memory of the PSR-9000. For sampling purposes,
memory can be expanded to a maximum of 65 MB, by installing SIMM modules.
Disk
The PSR-9000 also allows you to store your data to floppy disk, an optional hard disk drive, or
an external (optional) SCSI device (such as a hard disk drive, or removable storage).
