Method of self-refresh in large memory arrays

A method of self-refresh in a memory array includes initializing a programmable refresh counter of a memory module to an offset value from at least another memory module in the memory array. A data line carrying a system-wide self-refresh indicator signal is interrogated to determine whether any mem...

Summary:A method of self-refresh in a memory array includes initializing a programmable refresh counter of a memory module to an offset value from at least another memory module in the memory array. A data line carrying a system-wide self-refresh indicator signal is interrogated to determine whether any memory module is in a self-refresh mode. The self-refresh mode for the memory module is entered if the programmable refresh counter indicates that a self-refresh cycle is due, and it is determined that no other memory modules are in the self-refresh mode.
