Abstract: A semiconductor device may comprise a plurality of chips coupled in a ring structure, and the plurality of chips includes a first chip. Each of the plurality of chips may include a key port receiving or outputting a key to circulate the key through the ring structure. The first chip is configured to be in a standby state until an amount of available token becomes equal to or greater than an amount of required token to perform a specific operation in the first chip, when the first chip has the key.

Abstract: A semiconductor device may comprise a plurality of chips coupled in a bidirectional ring structure. The plurality of chips includes a first chip, and the first chip determines whether a token is required to perform a specific operation in the first chip. The first chip further determines whether an amount of an available token in the first chip is equal to or greater than an amount of the required token to perform the specific operation. When the amount of the available token is equal to or greater than the amount of the required token, the first chip performs the specific operation and then the first chip outputs one or both of a first portion of the available token in a first direction and a second portion of the available token in a second direction. The first direction is opposite to the second direction in the bidirectional ring structure.
