Abstract
In a plural line buffer type memory LSI, a line selection register 16 (holding an address for designating a line buffer) is added. The value of the line selection register 16 is previously updated by a memory access instruction having a room in an address. Thus, it is possible to maintain compatibility with input/output terminals of a general purpose memory LSI, or to prevent the increase in the number of input/output terminals, and also to prevent the increase of the memory access delay attributable to the restriction in connection with the issue of the commands. Accordingly, it is possible to maintain the compatibility with the general purpose memory LSI having no line buffer, or alternatively to prevent the increase of the memory access delay attributable to a restriction in an interval for issuing the commands.
