Abstract:
1. A method of reading data stored in a set in a multi-way set associative cache memory, the method comprising the steps of: generating a set selection signal by comparing a stored address with an address of the data; reading the data from a set selected by the set selection signal through a sense amplifier; and providing a circuit for transferring the set selection signal to the sense amplifier for reading the data, the circuit comprising: a first tri-state buffer for receiving the set selection signal in response to a first clock signal; a first flip-flop for receiving an output of the first tri-state buffer; a second tri-state buffer for receiving an output of the first tri-state buffer in response to a second clock signal; a second flip-flop for receiving an output of the second tri-state buffer; a first transmission gate for transferring an output of the second flip-flop in response to a state of a read-enable signal; and a second transmission gate for transferring the set selection signal in response to another state of the read-enable signal.
