    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.

    摘要翻译： 定时器从接收外部接入信号测量预定时间，并且在经过预定时间之后输出接入请求信号。 外部访问信号使存储器核心执行读取操作，并且访问请求信号使得存储器核心操作。 预定时间被设定为比存储器芯执行单次操作的核心操作时间长。 因此，当外部访问信号在比预定时间短的时间内变化时，存储器核不执行操作。 因此，即使当存储器核心不能正常操作的间隔提供外部访问信号时，也可以防止存储器芯故障并保留其中的数据崩溃。

    摘要： A semiconductor memory with a memory core for dynamically holding data in which a data collision at the time of the semiconductor memory making the transition from a standby state to a nonstandby state is prevented. A first buffer circuit inputs an enable signal for controlling a standby state or a nonstandby state. A second buffer circuit outputs a predetermined logic signal or a read/write signal for controlling the reading of data from or the writing of data to the memory core in accordance with the enable signal. A third buffer circuit outputs an inverted signal obtained by inverting the logic signal or the read/write signal in accordance with the enable signal. A control circuit controls the reading or writing of the data by the read/write signal outputted from the second buffer circuit. A data output control circuit controls the inputting of the data from or the outputting of the data to the outside by the inverted signal or the read/write signal outputted from the third buffer circuit.

    摘要： An external terminal receives an external signal so as to access the first and second memory chips. The test starting terminal receives a test starting signal activated when the first or second memory chip is tested and inactivated when the first and second memory chips are normally operated. The access signal generator converts the external signal to a memory access signal of the first memory chip. The first selector selects the external signal, which is a test signal, during activation of the test starting signal, selects the memory access signal during the inactivation of the test starting signal. That is, during the test modes, the first memory chip can be directly accessed from the exterior. For this reason, the test program for testing the first memory chip alone can be diverted as the test program following an assembly of the semiconductor device.

    摘要： Second memory cells of a second memory block each have an area 2a times (a is a positive integer) that of each first memory cell of a first memory block. Sizing the first and second memory cells in a predetermined ratio can make easily identical the dimensions of the first memory block and the second memory block. Consequently, it is possible to easily align peripheral circuits to lie around the plurality of first and second memory blocks, such as decoders. This also facilitates the wiring of signal lines to be connected to the peripheral circuits. This makes it possible to improve the layout design efficiency for a semiconductor integrated circuit. Thus, a plurality of types of memory blocks can be formed on a semiconductor integrated circuit efficiently. The semiconductor integrated circuit can be prevented from increasing in chip size depending on the layout design, owing to its simplified layout.

    摘要： A logic chip and a memory chip to be accessed by the logic chip are mounted in a single package. A pattern generator of the logic chip operates during a first test mode to generate internal test pattern for the memory chip. A pattern selector selects, during the first test mode, the internal test pattern outputted from the pattern generator, selects, during a second test mode, an external test pattern supplied via a test terminal, and outputs the selected test pattern to the memory chip. The memory chip mounted in the package is tested by use of, in accordance with a mode selecting signal, either the internal test pattern in the first test mode, generated within the logic chip, or the external test pattern in the second test mode, supplied from the exterior.
