Furthermore, because of the ASIC design of the Pippin hardware, the maximum RAM size that can be added is 32 MB. [44] Officially, Bandai produced memory upgrade modules of 2, 4, 8, and 16 MB. The memory chips are soldered onto a printed circuit board which is placed in a plastic housing, simplifying installation for the end user. [45]
The MMU was mostly compatible with the external 68851 that would be used with the 68020, [3] but being internal allowed it to access memory one cycle faster than a 68020/68851 combo. The 68030 did not include a built-in floating-point unit (FPU), and was generally used with the 68881 and the faster 68882 .
Memory modules of SK Hynix. 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 first memory modules were ...
[4] [5] Some disadvantages include generally being more expensive than desktop computers, a lack of customizability—most of the internal hardware such as the RAM and the SSD, especially in post-late-2010s machines, is soldered onto the system board—a lack of upgrade paths for the CPU, RAM, and technology of the display, and the difficulty ...
Rambus's RDRAM saw use in two video game consoles, beginning in 1996 with the Nintendo 64. The Nintendo console used 4 MB RDRAM running with a 500 MHz clock on a 9-bit bus, providing 500 MB/s bandwidth. RDRAM allowed N64 to be equipped with a large amount of memory bandwidth while maintaining a lower cost due to design simplicity.
Limits on physical memory for 32-bit platforms also depend on the presence and use of Physical Address Extension (PAE), which allows 32-bit systems to use more than 4 GB of physical memory. PAE and 64-bit systems may be able to address up to the full address space of the x86 processor.

A row data buffer may be from 32 to 4096 bytes long, depending on the type of memory. Rows larger than 32 bytes ignore some of the low-order address bits in the Activate command. Rows smaller than 4096 bytes ignore some of the high-order address bits in the Read command. Non-volatile memory does not support the Write command to row data buffers.
