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.
The Intellec 8 is able to address up to 16 K of memory and came with 5 K pre-installed. The Intellec 4 came with 1 K of PROM and 4 K of RAM for instruction memory, as well as 320 4-bit words of data memory, expandable to 2560 words. The Intellec 8 ran with a two-phase clock of 800 kHz, resulting in an instruction cycle time of 12.5 us.
On the x86-64 platform, a total of seven memory models exist, [7] as the majority of symbol references are only 32 bits wide, and if the addresses are known at link time (as opposed to position-independent code). This does not affect the pointers used, which are always flat 64-bit pointers, but only how values that have to be accessed via ...
The memory cells are laid out in rectangular arrays on the surface of the chip. The 1-bit memory cells are grouped in small units called words which are accessed together as a single memory address. Memory is manufactured in word length that is usually a power of two, typically N=1, 2, 4 or 8 bits.
A system designer should work with their memory and BIOS vendors to implement a suitable SPD programming. As such, the MRC is a part of the BIOS (or firmware ) of an Intel motherboard . George Chen, a research and development (R&D) director at ASUS , described it in 2007 as follows: [ 1 ]

In both real and protected modes, the system uses 16-bit segment registers to derive the actual memory address. In real mode, the registers CS, DS, SS, and ES point to the currently used program code segment (CS), the current data segment (DS), the current stack segment (SS), and one extra segment determined by the programmer (ES).
In computing, Physical Address Extension (PAE), sometimes referred to as Page Address Extension, [1] is a memory management feature for the x86 architecture. PAE was first introduced by Intel in the Pentium Pro, and later by AMD in the Athlon processor. [2]
