  • Patent number: 6643754
    Abstract: A method for managing computer memory includes maintaining multiple sets of free blocks of memory wherein a free block is added to a set based on its size. In response to a request for a block of a request size, a set of blocks is searched for a free block which is at least as large as the request size but smaller than the request size plus a threshold. If such a block is found, the block is allocated in its entirety. If such a free block is not found, a block at least as large as the request size maybe split and the request satisfied with the resulting split block. Methods for managing a block of contiguous persistent memory or storage and for coalescing adjacent free blocks using header information are also described.

    Abstract: A semiconductor memory device capable of improving common bus efficiency is disclosed. The device comprises an address shifting circuit for delaying an address by an n+m number of clock cycles in response to a clock signal, a control signal generating circuit for combining a column address strobe (CAS) latency of n-value and one of first and second operation signals to generate a control signal, and a switching circuit for outputting the address delayed by the n+m number of clock cycles output from the address shifting circuit in response to the control signal. The first operation signal indicates that the n-value of the CAS latency is less than a predetermined value and write latency is fixed. The second operation signal indicates that the n-value of the CAS latency is equal to or greater than the predetermined value and the write latency is variable.

  • Patent number: 6633504
    Abstract: A synchronous DRAM and method are provided in which main cells and spare cells are accessed by an external address during automatic refresh of a test mode. In the synchronous DRAM, a mode register setting circuit receives an external signal in response to a plurality of control signals to generate a mode register setting signal, during an automatic refresh operation in a test mode. An address selector selects and outputs an external address to the memory cell array, in response to the activation of the mode register set signal, during the automatic refresh operation in the test mode. The address selector selects and outputs an internal address to the memory cell array, in response to the deactivation of the mode register set signal, during an automatic refresh operation in a normal mode. Therefore, the main cells and the spare cells in the memory cell array are sequentially accessed and refreshed by the external address during the automatic refresh operation in the test mode.
