Apparatus, system and method for identifying semiconductor memory access modes |
摘要 |
An apparatus, system and method for identifying an access mode of a semiconductor memory in a data processing system, characterized by significant reduction of the possibility of erroneous identification of the access mode. A semiconductor memory has an access circuit bank with plurality of selectable circuits only one of which is activated, each selectable circuit respectively associated with a selectable semiconductor memory access mode, the access mode selection typically being accomplished by selectively blowing fuses associated with the corresponding selectable circuits. A semiconductor memory access mode is correctly identified by associating, in response to a test signal for determining the fuse status, the respective activated selectable circuit with its corresponding access mode.
