Dymec originally made a variety of products for the HP family, but over time became primarily an integrator, building test equipment and similar systems that were used by HP. In 1964, Kay Magleby and Paul Stoft began experimenting with the use of PDP-5 and PDP-8 computers to act as controllers for their complex test systems, but they felt the ...
PC-800 RDRAM operated at 400 MHz and delivered 1600 MB/s of bandwidth over a 16-bit bus. It was packaged as a 184-pin RIMM (Rambus in-line memory module) form factor, similar to a DIMM (dual in-line memory module). Data is transferred on both the rising and falling edges of the clock signal, a technique known as DDR. To emphasize the advantages ...
Computational RAM (C-RAM) is random-access memory with processing elements integrated on the same chip. This enables C-RAM to be used as a SIMD computer. It also can be used to more efficiently use memory bandwidth within a memory chip. The general technique of doing computations in memory is called Processing-In-Memory (PIM).
A gaming computer, also known as a gaming PC, is a specialized personal computer designed for playing PC games at high standards. They typically differ from mainstream personal computers by using high-performance graphics cards , a high core-count CPU with higher raw performance and higher-performance RAM .
The 1103 is a dynamic random-access memory (DRAM) integrated circuit (IC) developed and fabricated by Intel.Introduced in October 1970, the 1103 was the first commercially available DRAM IC; and due to its small physical size and low price relative to magnetic-core memory, it replaced the latter in many applications.
It refers to the average time it takes to perform a memory access. It is the addition of the execution time for the memory instructions and the memory stall cycles. The execution time is the time for a cache access, and the memory stall cycles include the time to service a cache miss and access lower levels of memory. If the access latency ...
In 1980, the price of a 16 kW (kiloword, equivalent to 32 kB) core memory board that fitted into a DEC Q-bus computer was around US$3,000. At that time, core array and supporting electronics can fit on a single printed circuit board about 25 cm × 20 cm (10 in × 8 in) in size, the core array was mounted a few mm above the PCB and was protected ...
