DEC 54-21225-JA 1MX32,60NS EDO DRAM MEMORY

Description

The DEC 54-21225-JA is a memory module featuring 1 Megabyte (1M x 32-bit) of EDO DRAM (Extended Data Out Dynamic Random-Access Memory). EDO DRAM was an enhancement over standard FPM (Fast Page Mode) DRAM, allowing for faster data transfer by enabling the next memory access to begin before the previous one was completely finished. This overlap significantly improved performance in systems that supported it. With an access time of 60 nanoseconds (60ns), this module provides relatively quick data retrieval for its generation. The '1MX32' designation indicates that the module contains memory chips organized to provide a 32-bit data width, which is common for main system memory in many architectures of the era. It is typically found in a 72-pin SIMM (Single In-line Memory Module) form factor, which was prevalent in PCs and workstations from the mid-1990s. This specific part number is associated with Digital Equipment Corporation (DEC), a prominent computer manufacturer during that period. This EDO DRAM module would have been used to upgrade or populate memory in compatible DEC systems or other machines that utilized EDO memory technology. Its inclusion signifies a specific point in the evolution of computer memory, bridging the gap between older DRAM and the subsequent SDRAM generations.
