DEC MS44-DC MV4000 / VS4000-90 64MB PARITY MEMORY ( 4 16MB 54-19103-CA

Product Description

The DEC MS44-DC is a memory expansion module designed to augment the Random Access Memory (RAM) of compatible Digital Equipment Corporation (DEC) computer systems, specifically the MV4000 and VS4000-90 models. This module provides a total of 64MB of memory, which is crucial for improving the overall performance and multitasking capabilities of these workstations or servers. The inclusion of 'PARITY' in its description indicates that this memory features error detection capabilities. Parity memory works by adding an extra bit (the parity bit) to each byte of data stored. This bit is set in such a way that the total number of '1's in the byte (including the parity bit) is either always even or always odd, depending on the parity scheme used. When data is read, the system recalculates the parity and compares it to the stored parity bit. If they don't match, an error is detected, alerting the system to a potential data corruption issue. This feature is vital in environments where data integrity is paramount. This specific module is composed of four individual 16MB memory chips, totaling the 64MB capacity. The part number 54-19103-CA is associated with this memory configuration and ensures compatibility with the intended DEC systems. Upgrading the memory with modules like the MS44-DC can significantly enhance application responsiveness, allow for larger datasets to be processed, and improve the overall user experience on the supported DEC hardware.
