Internal command signal generator for memory e.g. DRAM, generates memory-internal command signal at time point dependent on memory-internal command signal

摘要

A command input (212) receives a memory operation command (SP-OP-BEFEHL) for performing a memory operation in a memory system (232). A clock signal input (216) receives an external clock signal (CLK). An output (228) provides a memory-internal command system (INT-BEFEHL) on a command signal wire of the memory system. A command signal generator (220) uses the memory operation command to generate the memory-internal command signal at a time point dependent on the command signal (INT-BEFEHL). The command signal generator is adjustable, optionally synchronous with a rising or falling edge of the external clock signal.
