[comp.sys.ibm.pc] 1 MB Toshiba Ram Chips

fink@vms.macc.wisc.edu (Jerry Fink - MACC & School of Nursing) (08/06/88)

What is the difference between the 1 MB Toshiba Ram chips, one version is
numbered 411000 and the other version is numbered 511000?

                        Thanks

Looking in the "Toshiba MOS Memory Products Databook" released March 1988,
I find no reference to a 411000 series product.  There are 8 different
51100x products.  There are also some 41000 MODULES all of which are made
up of 4 1Megabit SOJ packages and are arranged as 1Meg x 4bits, the differences
between them being access mode.  The 41000's appear to be made out of 4
51100x products.

BTW, SOJ stands for "Small Outline J lead", it is a package type.
