    摘要: A memory controller connected to memory includes: an address reception unit for receiving an address code externally input together with a command; and a command conversion unit for outputting to the memory an MRS command to change the internal settings of the memory based on the address code when the address code input together with a first command specifies an address space for which the memory is not implemented.

    摘要: A timer measures a predetermined time from the reception of an external access signal, and outputs an access request signal after the predetermined time has elapsed. The external access signal causes a memory core to execute a read operation, and the access request signal causes the memory core to operate. The predetermined time is set to be longer than a core operation time for the memory core to perform a single operation. The memory core thus performs no operation when the external access signal varies in a time shorter than the predetermined time. Consequently, it is possible to prevent the memory core from malfunctioning and data retained therein from crashing even when external access signals are supplied at intervals at which the memory core is unable to properly operate.

    摘要: A memory system that can enhance yield without increasing the chip size and without degrading the access time. A single-bit error determination circuit references parity bits required to configure a code capable of correcting a single-bit error, and determines a single-bit error to be corrected; and a double-bit error detection circuit references one redundant bit added to the parity bits, detects a double-bit error, and enables or disables the double-bit error detection in accordance with a selection signal.

Further, a semiconductor device including a memory cell array formed by arranging a plurality of memory cells and a word line reset level generating circuit for generating a negative potential makes it possible to vary the amount of a current supply of the word line reset level generating circuit when non-selected word lines are set to a negative potential by applying the output of the word line reset level generating circuit to the non-selected word lines, and varies the amount of the current supply of the negative potential in accordance with the operation of the memory cell array. Furthermore, in a semiconductor device including a plurality of power source circuits each having an oscillation circuit and a capacitor, for driving the capacitor by the oscillation signal outputted by the oscillation circuit, at least a part of these power source circuits shares in common the oscillation circuit, and different capacitors are driven by the oscillation signal outputted from the common oscillation circuit.
