APPARATUS AND METHOD FOR REDUCING OPERATION TIME DELAY GENERATED DRAM HIDDEN REFRESH OPERATION

摘要

DRAM refreshes the method, and having can be reduced when start-up operation, the hiding equipment that the operating time occurred postpones. Device includes a database with multiple storage units, and the first data/address bus is connected to database, and the second data/address bus is connected to database, and cache is coupled to the second data/address bus, second and is connected to the locking of a data/address bus. Second data/address bus in writing commands i (i is a natural number) and is transmitted from the first data for caching to locking reading during second stage from memory by read response, when transmitting the locking in the first data to data library, (i+1) th circulations. Furthermore, the second data/address bus cache during being transferred to during second period is latched the first data read from database in response to writing commands i (i is a natural number), and (i+1) th is recycled and transmitted from the first data for being latched to cache reading.
