In order to upgrade the RAM, the manufacturer recommended using RAM modules of type 1.40.690003.5 for Z 9001, KC 85/1 and KC 87 systems. In addition, there was a freely configurable ROM module from Robotron, which can accommodate up to four EPROMs , each with a storage capacity of 1, 2 or 4 KB.
In computing, a memory module or RAM stick is a printed circuit board on which memory integrated circuits are mounted. [ 1 ] Memory modules permit easy installation and replacement in electronic systems, especially computers such as personal computers , workstations , and servers .
The Model D is preinstalled with 256, 512, or 640 KB of RAM. Lower-capacity machines are user upgradeable to 640 KB. [6] Motherboard revisions 7, 8, WC1 and WC2 come with 768 KB of RAM installed (640 KB available to the user). Some models have a monochrome/CGA selection switch, with a single port used for both modes. Some models have both a ...
The standards specify memory module label formats for end-user markets. [11] For example: 1GB 2Rx4 PC2-3200P-333-11-D2 is a 1 GB DDR2 Registered DIMM, with address/command parity function, using 2 ranks of x4 SDRAMs operational to PC2-3200 performance with CAS Latency = 3, tRCD = 3, tRP = 3, using JEDEC SPD revision 1.1, raw card reference ...
DDR2 is a 240-pin module, DDR is a 184-pin module. Notebooks have 200-pin SO-DIMMs for DDR and DDR2; however, the notch on DDR2 modules is in a slightly different position than on DDR modules. Higher-speed DDR2 DIMMs can be mixed with lower-speed DDR2 DIMMs, although the memory controller will operate all DIMMs at same speed as the lowest-speed ...

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 .
A module built out of 100 MHz SDRAM chips is not necessarily capable of operating at 100 MHz. The PC100 standard specifies the capabilities of the memory module as a whole. PC100 is used in many older computers; PCs around the late 1990s were the most common computers with PC100 memory.
