    摘要: Each program circuit outputs an operating specification signal indicating a first or second operating specification according to a program state. Each specification changing circuit is set by a corresponding block selection signal and outputs an operating specification signal indicating a second operating specification. Each timing control circuit changes an output timing of a precharge control signal for a bit line according to the operating specification signal. By the operating specification signal from the specification changing circuit, a failure can be detected in each memory block before programming a program circuit. Thereafter, the failure can be relieved by the program circuit. The output timing of the precharge control signal can be set for each memory block by a block selection signal without wiring a dedicated signal line for setting each specification changing circuit. Accordingly, increase in chip size can be minimized.

    摘要: A semiconductor memory and a refresh cycle control method that reduce a standby current by properly changing a refresh cycle according to the temperature of the semiconductor memory. A temperature detection section detects the temperature of the semiconductor memory. A cycle change control section sends a cycle change signal for changing a refresh cycle when the temperature of the semiconductor memory reaches a predetermined cycle change temperature. A refresh timing signal generation section generates a refresh timing signal and changes the cycle of the refresh timing signal in response to the cycle change signal. A constant current generation circuit generates an electric current for generating the refresh timing signal. A low-temperature constant current setting circuit designates the level of the electric current generated in the case that the temperature of the semiconductor memory is lower than or equal to the cycle change temperature. A high-temperature constant current setting circuit designates the level of the electric current generated in the case that the temperature of the semiconductor memory is higher than the cycle change temperature.

    摘要: A magnetic memory is composed of: a magnetoresistance element including a free magnetic layer; a first interconnection extending in a first direction obliquely to an easy axis of the free magnetic layer; a second interconnection extending in a second direction substantially orthogonal to the first direction; and a write circuit writing data into the free magnetic layer through developing a first write current on the first interconnection, and then developing a second write current on the second interconnection with the first write current turned on. The free magnetic layer includes: first to N-th ferromagnetic layers and first to (N−1)-th non-magnetic layers with N being equal to or more than 4, the i-th non-magnetic layer being disposed between the i-th and (i+1)-th ferromagnetic layers with i being any of natural numbers equal to or less than N−1. The free magnetic layer is designed so that antiferromagnetic coupling(s) between the j-th and (j+1)-th ferromagnetic layers is stronger than that between the first and second ferromagnetic layers, j being any of integers ranging from 2 to N−2.

    摘要: A plurality of switching transistors is provided, each connects power supply terminals of a plurality of first circuit blocks to a power supply line, respectively. Among the first circuit blocks, the power supply terminals of the first circuit blocks operating at different timings are connected by an internal power supply line. A power supply control circuit simultaneously turns on the switching transistors connected to the internal power supply line, in response to operation(s) of at least any one of the first circuit blocks connected to the internal power supply line. Since the switching transistors can be shared among the first circuit blocks not operating simultaneously, operation speed of the first circuit blocks can be increased. Since a total size of the switching transistors can be made small, standby current can be decreased. Accordingly, a semiconductor integrated circuit operating at a high speed can be constituted without increasing the standby current.
