As the name suggests
‘Intelligent RAM’ is the integration of Intelligence and RAM. Intelligence
stands for Microprocessor, and RAM, the random access memory which is the
volatile memory that is an important part of computing systems from desktop
computers to supercomputers. Intelligent RAM, or IRAM, merges processing and
memory into a single chip to lower memory latency, increase memory bandwidth,
and improve energy efficiency as well as to allow more flexible selection of
memory size and organization
The IRAM
technology was proposed by David Patterson, University of California, Berkeley,
U S A as an alternative for current memory-processor combination which has many
pit falls. It was implemented by a group of post graduate students lead by
Patterson.
Processor - Memory (DRAM) Gap or Latency
It is the delay time between the
performance of Microprocessor and RAM. Since processor and RAM are fabricated separately
in two fabrication lines the clock speed of them will vary in two different
rates creating a performance gap between them.
Memory Revenue
The memory revenue is
decreasing rapidly nowadays. Even though the need for DRAM chips is increasing
the DRAM manufacturers are not getting the benefit because of the high cost of
production. This makes the RAM manufactures to think of another alternative
which can reduce the cost of production to maintain the revenue as well as
their business.
