  • Patent number: 6094701
    Abstract: A semiconductor memory device is provided with a determination circuit and an address adder. The determination circuit determines whether a read start address selects upper-address banks B5-B8 or lower-address banks B1-B4. When the determination circuit determines that the lower-address banks are selected, the address adder increments a column address by 1. From the upper-address banks, data are read from the columns corresponding to the read start address. From the lower-address banks, data are read from the columns that are next to the columns corresponding to the read start address. Even when the upper-address banks are designated by the read start address, the data output from the lower-address banks corresponds to the next columns. Since there is no busy time during data output, successive access is enabled and the access cycle time can be as short as possible.

  • Patent number: 6014443
    Abstract: Cryptographic key data and data subjected to an operation by use of the cryptographic key data are previously stored in a memory cell array. A memory cell in which the cryptographic key data is stored is accessed and latched and the cryptographic key data is latched in a latch circuit before read out data from the memory cell array. After this, the latched data and data output from a sense amplifier are subjected to an operation by an arithmetical circuit to decode the data and the result of the operation is output as readout data.

  • Patent number: 5924123
    Abstract: For copy guard, an ROM comprises an address data determining circuit, an address sequence monitoring circuit, an error address data generating circuit, and an output selection circuit. The address sequence monitoring circuit monitors the addresses stored in the address data determining circuit and input addresses to determine whether or not the input addresses are in a predetermined sequence of the addresses in the address data determining circuit. The output selection circuit outputs data read from said memory cell array when the address sequence monitoring circuit determines that the address sequence of the input addresses coincides with the predetermined sequence of the addresses stored in the address data determining circuit and outputs error data generated by the error data generating circuit when a determination is made that the sequence of the input addresses does not coincide with the predetermined sequence.

  • Patent number: 5852575
    Abstract: A semiconductor memory including memory cells, word lines, bit lines, a row decoder, column decoder, a voltage-changing circuit, a sense amplifier, and an output circuit. Each memory cell stores multi-level data. The row decoder selects one of the word lines in accordance with an address signal. The voltage-changing circuit generates different voltages, which are applied to the row decoder. The different voltages are sequentially applied from the voltage-changing circuit to the word line selected by the row decoder. The column decoder selects a bit line every time the potential of the word line changes. The sense amplifier detects the data read from the memory cell onto the bit line every time the potential of the word line changes. The output circuit converts the data to code data.

  • Patent number: 5579279
    Abstract: A memory system having an input buffer, an address counter, an address decoder, and a memory-cell array. Address signals are supplied to the memory-cell array. In the system, a true-address data determining section has wires or a circuit storing an internal address specific to the system. A false-data generating circuit generates false data when the internal address is in a false data area, and the false data is input to an output selecting circuit. A true-address data area detecting circuit compares the true-address data EAi with the internal address consisting of the address signals supplied from an address counter, and generates a signal REAL when the internal address is in a true-address data area. The output-selecting circuit selects the false data or the data read from the memory-cell array through a sense amplifier, in accordance with whether the signal REAL is at high level or low level. The data stored in the memory-cell array consists of true data items and false data items.
