No. The current crop of machines referred to as ASICs around here are built for SHA256 hashes. ASIC simply means "application-specific integrated circuit", it is not specific to bitcoin, or to SHA256 or scrypt or anything. It is a generalized term for hardware that performs specific tasks.


ASICs are a piece of hardware, written in silicon. There can not be new software versions. New designs must be created and new machines must be built for scrypt, or any purpose.


This would require a lot of engineering time to figure out. It also depends on how good those engineers are. Scrypt is a very complex algorithm that attempts to punish you by requiring more memory the faster you go. It is called a time memory tradeoff. In contrast, SHA256 is rather simple: faster is better.
