Title: Chip selection signal generation circuit
Inventor: OKAMOTO HISANORI
IPC: G06F12/06
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To attain the continuous assignment of addresses even if plural RAMs of different capacity are integrated by making every comparator supply a chip selection signal to the RAM as long as an input address is included in its on address range. SOLUTION: The address signals are supplied to comparators 1 to 4 of a chip selection signal generation circuit 10 and then compared with the boundary addresses which are inputted as the upper and lower limit values. For instance, the comparator 1 compares an input address with the boundary address value SA1 and SA2. A chip selection signal CS1 is outputted for selection of a prescribed RAM when the input address is set between both values SA1 and SA2, to be more precise, in a range larger than the SAI and smaller than SA2. As a result, the addresses can be continuously assigned to a memory as long as the boundary address values SA1 to SA5 are decided in response to the capacity and array of RAMs to be used even when plural RAMs of different capacity are optionally combined into a single memory.
