The two main types of volatile random-access semiconductor memory are static random-access memory (SRAM) and dynamic random-access memory (DRAM). Non-volatile RAM has also been developed [ 3 ] and other types of non-volatile memories allow random access for read operations, but either do not allow write operations or have other kinds of ...
It became the basis for today's dynamic random-access memory (DRAM) and almost all other memory types such as SRAM and FLASH memory. DRAM was instrumental in changing the world of computing through faster and higher capacity memory access. [1] Today, DRAM is used pervasively across many devices from servers to personal computers to mobile devices.
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).
Microprocessor access to off-chip memory costs time and power, however, significantly limiting processor performance. For this reason computer architecture employing a hierarchy of memory systems has developed, in which static memory is integrated with the microprocessor for temporary, easily accessible storage (or cache) of data which is also ...
Ferroelectric RAM (FeRAM, F-RAM or FRAM) is a random-access memory similar in construction to DRAM but using a ferroelectric layer instead of a dielectric layer to achieve non-volatility. FeRAM is one of a growing number of alternative non-volatile random-access memory technologies that offer the same functionality as flash memory.
Nutshell description of a RASP: The RASP is a universal Turing machine (UTM) built on a random-access machine RAM chassis.. The reader will remember that the UTM is a Turing machine with a "universal" finite-state table of instructions that can interpret any well-formed "program" written on the tape as a string of Turing 5-tuples, hence its universality.
Double Data Rate 4 Synchronous Dynamic Random-Access Memory (DDR4 SDRAM) is a type of synchronous dynamic random-access memory with a high bandwidth ("double data rate") interface. Released to the market in 2014, [ 2 ] [ 3 ] [ 4 ] it is a variant of dynamic random-access memory (DRAM), some of which have been in use since the early 1970s, [ 5 ...
In computer science, random-access machine (RAM or RA-machine) is a model of computation that describes an abstract machine in the general class of register machines.The RA-machine is very similar to the counter machine but with the added capability of 'indirect addressing' of its registers.
