5,319,755
Integrated circuit I/O using high performance bus interface
Abstract
An apparatus for storing and retrieving data is described. The apparatus includes a circuitry for initiating data transmission, a first memory, a second memory, and a multiline bus for transferring control information, addresses, and the data. The control information includes information for selecting one of the first and second memories without using any separate memory select line. Configuration circuitry is provided for assigning a first identification value to the first memory and a second identification value to the second memory. The configuration circuitry includes a first reset line for coupling the circuitry for initiating data transmission to the first memory, a second reset line for coupling the first memory to the second memory, a first identification register for the first memory, a second identification register for the second memory, circuitry for generating a first reset signal and a second reset signal and for sending the first and second reset signals to the first identification register, circuitry for propagating the first and second reset signals from the first identification register to the second identification register, circuitry for resetting the first and second identification registers in response to the first reset signal, and circuitry for setting the first identification register to the first identification value and the second identification register to the second identification value in response to the second reset signal.
