Title:
MEMORY SYSTEM AND METHOD FOR PASSING CONFIGURATION COMMANDS
Document Type and Number:
WIPO Patent Application WO/2013/016291
Kind Code:
A3
Abstract:
A memory system is provided. In the system, there are first and second sets of dynamic random access memories (DRAMs)(16A-D) and a system register (14). Each DRAM (16) has at least a first and a second addressable mode register (18A-D), where the binary address of the second mode register is the inverted binary address of the first mode register. The system register (14) has an input configured to be coupled to a controller (12), an output coupled to the first set of DRAMs via first address lines and an inverted output coupled to the second set of DRAMs via second address lines. The system register (14) is configured to receive mode register set commands including address bits and configuration bits at the input and to output the mode register set commands non-inverted via the output to the first set of DRAMs and in inverted form via the inverted output to the second set of DRAMs.
