The MM-Series of memory modules use a dedicated memory interface to maximize CPU/memory performance.  These memory expansion modules provide high performance, 32-bit parity DRAM memory for the Multibus I and Multibus II boards.  Memory addressing for the memory module is controlled by the host CPU board over the memory module interface.  The maximum system RAM size is 64MB.

 

The dynamic RAM memory of the memory modules is accessed through the dedicated memory module interface. The MM memory module is designed for direct transfer of data between the CPU and the memory module without accessing the MULTIBUS interface.  The memory modules use a 32-bit wide data path with storage for byte parity that can accommodate 8-bit byte, 16-bit or 32-bit word data transfers.  In addition, the data path is capable of independent byte operations.  This means that one byte can be written while the other three bytes (or any other combination) can be read.

 

One parity bit is provided for each of the four, 8-bit bytes in the 32-bit wide data path.  For special applications, the parity bits can serve as data bits making possible 9-, 18-, or 36-bit data transfers.  The module protocol supports standard dynamic RAM READ, WRITE, RAS only REFRESH cycles, and CAS before RAS REFRESH.

 

The SBC MM-series memory modules are easily installed by the user.
