Ok, I've seen greeting cards with those music, and those Tetris Handheld game which is sold at 99¢ in a cheap bargain shop.
All of them are similar - one black blob with some squarish thing in the center. Maybe it's a die.
What's in it anway? Mask ROM? Programmable Logic Device? Microcontroller?
And do they program those like in µC and then place them in the product afterwards?
It's a burning question, since I can't find the answer in the net. Enlighten me.
