A memory device in which a plurality of data can be read out by giving one address and a plurality of data can be read out without adding more address lines is provided, and therefore, the circuit integration is not degraded. The memory device includes: m memory array banks, each including row and column address decoders; a first circuit for receiving one address and generating m row addresses and n column addresses by shifting the one address by a predetermined value for each of the m row and n column addresses; and a second circuit for inputting each of the generated m row and n column addresses to the corresponding row and column address decoders of the m memory array banks.

A method of the present invention relates to a method of blending a plurality of pixels on a texture map and to a plural pixel blending circuit and image processing device using this is disclosed. The method of blending a plurality of pixels on a texture map corresponding to the pixels constituting a polygon, thereby finding texture data to be pasted on to the pixels constituting the polygon, includes the steps of: determining whether or not there are transparent pixels in said plurality of pixels on the texture map; if there are no transparent pixels, blending said plurality of pixels on the texture map in accordance with the ratio with which a pixel constituting the polygon corresponds therewith; if some of the plurality of pixels on the texture map are transparent pixels, substituting the transparent pixels by other adjacent pixels which are not transparent; and if all of the plurality of pixels on the texture map are transparent pixels, ignoring the plurality of pixels on the texture map.

A video game device is disclosed which is composed of a console apparatus in which a processor is installed to execute a game software program. The video game device also includes a memory device, such as a memory cartridge which is removably attached to the console apparatus and which stores the game program. An enhanced function board is attached to the main body of the video game device for improving and enhancing the functions of the video game. The enhanced function board includes a pair of buses, first and second digital processors connected to the buses, a FIFO memory connected between the buses, and an interface circuit connected to the pair of buses. The interface circuit operates to connect the first and second digital processors to the processor of the video game device.
