ABSTRACT:
A memory control circuit includes a control register having a memory capacity of m bits or smaller for setting information necessary for controlling the memory, input pins to which m-bit test data is input in parallel, an extension circuit for extending the data input to the input pins to n-bit data, and a first selection section for selectively inputting n-bit data supplied from the extension circuit or a CPU based on a mode signal to switch between a test mode and a normal mode. The memory control circuit further includes a degeneration circuit for compressing n-bit data to be output in parallel to the CPU to m-bit data, a second selection section for selecting m-bit data compressed by the degeneration circuit or lower m-bit data in n-bit data to be output to the CPU based on a switch signal, and output pins for outputting the m-bit data selected by the second selection section in parallel.
