Cell switching apparatus and a cell switching system
 This invention provides a cell switching apparatus having buffer memories in which accesses of a plurality off cells can be implemented in one-cell time. The cell switching apparatus arranges a plurality of buffer memories, in which accesses of a plurality of cells can be performed, in parallel, and schedules a score table so that the writing and reading out operations may not overlap. Accordingly, the incoming lines may be increased lip to (the number of incoming lines n)=(the number of buffer memories p-1).times.(the number of outgoing lines m) without increasing the access speed of the buffer memories.
