专利汇可以提供Memory control system专利检索,专利查询,专利分析的服务。并且A memory control system for controlling the communication between a plurality of users and a memory is disclosed. The memory which is random-access memory, is organized in a unique way in that it is divided into pages, each page containing a plurality of groups, each group including a plurality of addressable locations. Each page also includes page control words and a separate group link word for each group. Fields of the page control words are used for page linking to form page lists and to indicate the availability of groups for assignment, while the fields of the group link words are used for the linking of groups to form strings of groups. The memory also includes a specific addressable location in which a system control word is stored. Various fields of the system control word are used in controlling the initial assignment of pages, the reclamation of pages no longer needed by users, and the dynamic reassignment of pages to users. The memory also includes a separate user control word for each user. Various fields of a user control word are used to point to a user''s page list, to point to a page in which group space is available for assignment, and to point to reclaimed groups. The memory control system includes a plurality of generators for generating, at clock cycle time, the addresses of any one of the control words. The memory control system also includes logic circuitry for automatically executing any one of a plurality of coded operations, commanded by any of the users.,下面是Memory control system专利的具体信息内容。

1. A method for dynamically locating memory storage locations, comprising: receiving a unit of data of a sequence of such units from a user; assigning a storage location to said unit of data in a computer memory; associating a group link word to said unit of data, said group link word containing information denoting the locations in the memory of the previous and subsequent data units in said sequence of data units; referring to one of said group link words to ascertain the location of one of said units in said sequence of data units; and finding said one of said sequence of data units and using it to locate one or more additional units of data in said sequence of units of data.
2. The method of claim 1 further characterized by the assignment of a storage location into said unit of data being carried out by referring to a system control word whose content is indicative of the availability of locations in said memory for said user.
3. The method of claim 1 further characterized by the additional step of ascertaining the locations previously assigned to said user and the availability of previously assigned locations for use by said user by means of reference to a list control word also assigned to said user.
4. The method of claim 1 further characterized by the assignment of a storage location to said unit of data in the computer memory being within a plurality of user storage pages assigned to said user, each page having a page header word which includes a page list link portion denoting the location of a different related page assigned to the same user, said related page also having a page header word including a page list link portion denoting another different related page assigned to the same user, said page and all said related pages thereby defining a list of pages assigned to the same user.
5. The method of claim 4 further characterized by said user storage pages including a plurality of groups of locations for storing data words and a location for storing said page header and the content of a part of said page header word being indicative of groups of locations available for storing data from the user to which the page is assigned.
