I am designing a new board that uses 1 Meg by 9 DRAMS. Clearly, it is cheaper (and uses less board space) to use regularly-available SIMMs or SIPs than to use individual chips. These SIMMs and SIPs are used in scads of PC clones, PS/2s, Macs, etc.; they are often cheaper than 9 1Mx1 DRAM chips. Question: Which should I use, SIMMs or SIPs ?? The SIPs have through-hole pins, and no edge connector, so they appear to take less board-to-board space; SIMM sockets, however, are available to mount the SIMM at an angle, reducing their height (and board-to-board space). Connectors are readily available for both, and prices are comparable. What are the advantages/disadvantages of SIMMs and SIPs ?? Thanks in advance, Tom Roberts att!ihlpl!tjrob TJROB@IHLPL.ATT.COM
