- It's a blob-packaged ROM chip. Some manufacturers support
- a direct chip-on-board mounting for their products (Rockwell is
- one, and IBM and Intel have done it as well). This saves money
- (not much), and is showing up in a few consumer items.
-
- Some chip houses, of course, will not ship dice, only
- packaged IC's; you can't rip the chip out after it has been
- packaged. And, it may be awkward to do final QC (full testing
- of the chip) without putting it in a standard DIP or other package
- first.
