发明名称 Method for operating a semiconductor memory and semiconductor memory
摘要 An additional test mode is introduced in a semiconductor memory. A multiplicity of word lines are simultaneously activated by a word line decoder in the test mode. After a potential equalization of complementary bit lines, a logic "0" or a logic "1" is applied to an equalization circuit via a voltage generator. It is thus possible for the entire memory cell array to be preallocated an identical data value or, in strip form, alternating data values. Test time is thereby saved.
