... Bipolar counterparts. A further advantage of the WS57C49C over Bipolar PROM devices is the fact that it utilizes a proven EPROM technology. This enables the entire memory array to be tested for switching characteristics and functionality after assembly. Unlike devices which cannot be erased, every WS57C49C in a windowed package is 100% tested with worst case test patterns both before and after assembly ...
