Abstract
The outputs of selectors to N are respectively connected to the data inputs DI to DIN of a RAM A. One inputs of selectors to N are respectively connected to the data outputs DO to DON of the RAM A, the other inputs are connected to corresponding outputs of the selectors to N. The outputs of the selectors to N are connected to data inputs D of respective scan flip-flops to N. Not in a RAM test mode, data input lines to N are selected by the selectors to N to provide to the data inputs DI to DIN of the RAM A and to the scan flip-flops to N through the selectors to N, respectively.
