data bar polling

A method, used to determine whether the write operation in a memory is complete, wherein the memory is put into the read mode after initiating the write mode; if writing is complete, the outputs take on the addressed stored data, or if writing is not complete, the specified output(s) take on the complement of the last bit(s) written.

NOTE If writing is not complete: (a) in older devices, normally all outputs take on the complement of the last bits written; (b) in more modern byte-wide memories, only the most significant output takes on the complement of the last bit written; (c) in word-wide memories, the most significant output of the least significant byte, the most significant output of the entire word, or both of these outputs take on the complement of the last bit written.
