Stacked flash/ram memory

I have seen some stacked flash/ram memory modules available on 
various manufacturer websites. However all the modules are 
bga. Does anyone know if there are any that are any available 
in a LQFP or other leaded form.

It would certainly make things easier for small microcontroller projects 
to have flash and ram in one chip.

Do you mean "small" (uncomplicated) or "small" (low PCB area)
projects?

For the former, pick a microcontroller that has flash and RAM on-chip.

The chips you're talking about are designed for the latter
application. BGA yields a much higher board density than any leaded
package, so I wouldn't expect to see these high-density parts in any
other form.

These parts are designed for one thing, cell phones.  If you try to use
them in one of your small projects, you will likely find that they are
made of unobtainium and have correspondingly long lead times.
