Product Description
The IBM 09P2705 is a 256MB memory module utilizing DDR SDRAM technology, specifically designed in the Micro-DIMM form factor. This compact form factor is typically found in ultra-portable devices, small form factor PCs, or specialized embedded systems where space is a premium. Operating at a clock speed of 266MHz, it corresponds to the PC2100 standard, offering a data transfer rate of 2100 MB/s. The module is organized as 2Rx8, indicating it is dual-ranked with eight memory chips per rank, which can sometimes offer performance benefits in certain memory controllers. This particular module features a CAS Latency (CL) of 2.5, meaning it takes 2.5 clock cycles for the memory to respond to a column access strobe command. This latency is typical for DDR-266MHz memory. As a Non-ECC (Non-Error-Correcting Code) module, it is suitable for applications where the highest level of data integrity is not paramount, such as in consumer electronics or general computing tasks. The Micro-DIMM form factor is physically smaller than standard DIMMs and SO-DIMMs, requiring specific slot compatibility on the motherboard. This IBM memory module is a component designed to provide essential memory capacity for devices that cannot accommodate larger memory modules. Its 256MB capacity is modest by today's standards but was significant for the era and type of devices it was designed for. Compatibility is key, as Micro-DIMMs are not interchangeable with other DIMM types. Users needing to replace or upgrade memory in compatible systems would look for modules with these exact specifications to ensure proper function.
