    摘要: A memory cell array 1 has the arrangement of a plurality of cores, each of which comprises one block or a set of a plurality of blocks, each block defining a range of memory cells serving as a unit of data erase. A core selecting part for selecting an optional number of cores to write/erase data is provided for writing data in memory cells in cores selected on the basis of a write command and for erasing data from selected blocks in cores selected on the basis of an erase command. Thus, there is realized a free core system capable of reading data out from memory cells in unselected cores while writing/erasing data in cores selected by the core selecting part.

    摘要: A semiconductor memory device having a partial activation framework, which provides an efficient page mode operation while operating in a partial activation mode. Control circuits and methods are provided to enable a page mode operation (for read and write data accesses) in a semiconductor memory device (such as a DRAM, FCRAM) having a partial activation framework, resulting in an improved data access speed when data is written/read from memory locations having the same wordline address. In one aspect, a method for accessing data in a memory device comprises activating a first wordline corresponding to a first address to perform a data access operation, receiving a second address after the first address, if the second address is the same as the first address, generating a page mode enable signal for maintaining an activated state of the first wordline corresponding to the first address while activating a second wordline corresponding to the second address, and deactivating the first and second wordlines in response to disabling of the page mode enable signal.

    摘要: A negative word line driver employs devices to maintain the potential difference between the active word line signal and the inactive word line signal while reducing the need for a significant negative voltage supply. One form of the negative word line driver employs an isolation element to couple the word line to ground when the inputs to the word line driver indicate the word line should not be active, while the word line is also coupled to the negative voltage supply. Another form of the form of the negative word line driver receives as inputs the voltages to be driven on the word line and can be implemented with fewer transistors but still allows the word line to be driven at a negative voltage with a reduced negative voltage supply.

    摘要: A clock generating circuit for a pseudo dual port memory incorporates feedback, delays, and latches to ensure that the write (read) operation clock pulse is sufficiently spaced in time from the read (write) operation clock. The clock generating circuit receives an external clock, a read enable signal, a write enable signal, and a reset signal as inputs. Advantages include minimization of the clock cycle time and operation unaffected by the duty ratio of an external clock. Delay circuitry may be added such that the generated clock signal has sufficient fan out and is sufficiently stable.

    摘要: Synchronous semiconductor memory devices and methods of operating are provided. The device has a latency N and includes a memory cell array, a stack unit having N storage units and a frequency detector that provides an output signal based on the relationship of the frequency of operation clock to a predetermined frequency. A control circuit controls the stack unit in response to the output signal of the frequency detector. The control circuit latches data read from the memory and controls the stack unit so that the latched data is stored from a clock cycle when a read command is sent until an N-th cycle afterwards if the clock frequency is greater than the predetermined frequency and delays the latched data for one cycle and controls the stack unit so that the delayed data is stored from one cycle after the read command is sent until an N+1 cycle afterwards.
