摘要： A memory system includes at least one or more memory module boards identical in construction and a single computer board containing the control circuits for controlling memory operations. Each board plugs into the main board and includes a memory section having a number of rows of memory chips and an identification section containing circuits for generating signals indicating the board density and the type of memory parts used in constructing the board's memory section. The main board control circuits include a number of decoder circuits which couple to the identification and to the memory section of each memory module board. The decoder circuits receive different address bit combinations of a predetermined multibit address portion of each memory request address. In response to signals generated by the identification sections of the installed memory boards, the decoder circuits are selectively enabled to decode those bit combinations of the address portion specified by the sections for enabling successive addressing of all of the blocks of location within the system.

摘要： A memory subsystem which couples to a multiword bus for processing memory requests received therefrom includes at least a pair of independently addressable dynamic memory module units. Each memory unit includes a number of rows of random access memory (RAM) chips. The subsystem further includes an adder circuit, a pair of tristate operated address register circuits and timing circuits. The address circuits include a pair of tristate operated address registers which couple to the bus and to the set of address lines to each memory unit. In response to a memory request, the registers store row and column address portions of a chip address of the memory request. A multibit adder circuit which couples to the bus is connected to increment by one the low order column address portion when the least significant address bit of the memory request indicates a subboundary address condition thereby enabling access to a pair of sequential word locations. Whenever a memory request specifies an address which cannot access a double word, boundary circuits upon detecting the condition cause the timing circuits to generate only timing signals necessary for accessing the first word location.

摘要： A memory controller controls the operation of a number of memory module units and includes a number of queues which couple to the module units. Each queue includes an address queue register, a control queue register and a data queue register. Each address queue register has tristate control for independent operation. Control circuits which couple to the queue address, control and data registers assign memory cycles between queues on an alternate basis when the queue control registers store requests which are being processed. This enables the interleaving of memory requests which eliminates processing delays particularly in cases where such requests involve multiword transfers over successive memory cycles of operation.

摘要： Soft error rewrite control apparatus is included within a memory system for rendering the semiconductor memory modules less susceptible to single bit errors produced by alpha particles and other system disturbances. During a number of successive memory cycles occurring at a predetermined rate, the soft error rewrite control apparatus enables the read out of information stored within each module location, the correction of any single bit errors contained therein and the rewriting of the corrected information back into such location. Diagnostic apparatus is further included which is connected to place the memory system in a state for testing and verifying the operation of the soft error control apparatus. Also, the diagnostic apparatus is connected to condition the soft error control apparatus for operating in a high speed mode enabling the read out correction and rewriting of each location to take place within a minimum amount of time. By monitoring the status of the information being corrected, the diagnostic apparatus is able to signal whether or not the soft error control apparatus is operating properly.

摘要： Apparatus and a method for generating timing signals to be utilized in latched type memories only when the address signals are valid. A CAS signal is generated in response to an RAS signal via a device which tracks the worst case delay of memory address signals and does not permit the application of the CAS signal to memory until the worst case delay of the memory address signals has been accounted for.A memory array is comprised of any combination of latched or non-latched tri-state memories. The latched memories are coupled to a data bus utilizing conventional TTL circuits in combination with a power driver to simulate conventional tri-state buffer circuits. When the power driver/drivers remove(s) power from TTL circuits, the tri-state characteristics are simulated; whereas when the power driver applies power to the TTL circuits, they operate in their normal mode and present a normal impedance between the data bus and data-out lines of the memory array.

摘要： Apparatus is included in a main memory subsystem of a data processing system which receives multibyte data from a plurality of input/output devices connected to a common bus. During a write cycle of operation, a device applies the multibyte data signals together with associated parity bits for writing into an addressed storage location of memory. During the write cycle, error encoder circuits generate check code bits from the multibyte data and parity bits which are coded to signal selectively the presence of a multibyte uncorrectable error condition in accordance with the parity bits from a device. During a read cycle of operation, error detection and correction decoder circuits connected to the memory in response to the data and check bits read out from an addressed location are operative to generate a number of syndrome bits. These bits have a predetermined characteristic for indicating the existence of an uncorrectable error condition when one or more data bytes were in error and there was a single bit error in memory.
