Semiconductor storage device conducting a late-write operation and controlling a test read-operation to read data not from a data latch circuit but from a memory core circuit regardless of whether a preceding address and a present address match each other |
摘要 |
A semiconductor storage device conducts a late-write operation. The semiconductor storage device comprises: a memory core circuit storing data; a data latch circuit storing preceding data corresponding to a preceding write-operation; an address compare circuit comparing a preceding address corresponding to the preceding write-operation and a present address corresponding to a present read-operation so as to determine whether the preceding address and the present address match each other; and a control circuit. The control circuit controls a test read-operation to read data from the memory core circuit regardless of whether the preceding address and the present address match each other.
