Midazolam (Dormicum) has this property, and is routinely used in anaesthesia
for that purpose (patient partially wakes up during surgery, has an unpleasant
experience, the drug is administered to erase short time memory (mostly)).

Many other drugs (some antibiotics, also alcohol) also have this property.

Speaking of alcohol: anyone who considers that consciousness is a boolean
property is very welcome to a personal experiment involving measuring 
correlation of the degree of awareness with alcohol content in blood, 
titrating until loss of consciousness.

I understand such drugs are currently considered for an early therapy for 
traumatic incidents (if you can't remember it, you won't be traumatized by
recurring memories).
