Abstract

An ATM cell processing apparatus including a DRAM for a frame producing buffer of a frame producing unit. In order to absorb the anisotropy of the access rate of the DRAM access, the random access mode of the DRAM access is always used. To compensate a drop in access rate in this case, the DRAM is arranged is an array form and each cell is divided. Resultant partial cell data are written into and read from respective DRAM banks in order. As a result, a fast cell buffer having a large capacity can be formed. The present cell buffer can be applied to a FIFO and the like as well.
