    摘要: Disclosed is a semiconductor memory device having a data retention operating mode. When an entry into the data retention operating mode is performed, parity information on data of the memory cells is calculated and the error correction on the memory cells is carried out at a time of an exit from the data retention operating mode, by an ECC (Error Correction Circuit). The semiconductor memory device includes means for outputting from an NC pin flag information indicating that the semiconductor memory device is the one including the data retention operating mode, that the exit processing from the data retention operating mode is under way, and that the error correction cannot be performed.

    摘要: In a semiconductor memory device which is intended to have a smaller sense amplifier forming area to match with small-sized bit lines, first bit lines BL (e.g., BL2a) are formed on a first layer, and lines M2 (e.g., M2a) are formed on a second layer and connected to the first bit lines in a first connecting area located between a first memory cell area and a sense amplifier area. Second bit lines BL (e.g., BL1c) are formed on the first layer, and lines M2 (e.g., M2c) are formed on the second layer and connected to the second bit lines in a second connecting area located between a second memory cell area and the sense amplifier area. As a result, the lines M2 on the second layer can have a smaller line interval.
