... V per Truth master use the BUSY signal as a write inhibit signal. Thus on the IDT70V261 SRAM the BUSY pin is an output if the part is used as a master (M/S pin = slave (M/S pin = two or more master parts were used when expanding in width, a split decision could result with one master indicating BUSY on one side of the array and another master indicating BUSY on one other side of the array ...

... How the Semaphore Flags Work The semaphore logic is a set of eight latches which are indepen- dent of the Dual-Port SRAM. These latches can be used to pass a flag, or token, from one port to the other to indicate that a shared resource is in use. The semaphores provide a hardware assist for a use assignment method called “ ...
