Patent ID: 8046527

Claim:
A method for communicating with a serial interconnection of a plurality of memory devices connected in-series, at least one of the memory devices having a temporary store element and a device identification associated with an address in the serial interconnection, the method comprising: sending a write command including a device identification, a write operation instruction and data stored in a data storage to the serial interconnection, the plurality of memory devices being configured to propagate the write command therethrough in response to a propagation control, at the at least one of the memory devices, determining whether it is selected based on the device identification included in the write command and the associated device identification, in a case of determination where the memory device is selected, a selection determination for writing being provided, writing the data to the temporary store element of the memory device in response to the selection determination for writing and the write operation instruction; at a later time, sending a read command including a device identification and a read operation instruction to the serial interconnection, the plurality of memory devices being configured to propagate the read command therethrough in response to the propagation control, at the at least one of the memory devices, determining whether it is selected based on the device identification included in the read command and the associated device identification, in a case of determination where the memory device is selected, a selection determination for reading being provided, reading the data written to the temporary store element of the memory device in response to the selection determination for reading and the read instruction, the read data being provided through the serial interconnection to the data storage.
