//
//   Geometry of the  DDR4 96 Pin  package for the Micron  MT40A1G16.
//
//
//   This is the geometry for the Micron  MT40A1G16  DDR4 SDRAM
//   which is a  16 Gbit part,  i.e.  1 Gig addresses by 16 bits wide.
//   This package has  96 SMD pads,  i.e. 6 Rows of 16 Pins
//
//   This geometry has the long axis of this component on the X axis.
//
//   The overall orientation of this geometry is pin A1 in the
//   North East corner.
//
//
//         T1   R1   .....   B1   A1   <--- pin #1 corner
//         T2   R2   .....   B2   A2
//         T3   R3   .....   B3   A3
//          .    .            .    .         Top-View
//          .    .            .    .         --------
//         T7   R7   .....   B7   A7
//         T8   R8   .....   B8   A8
//         T9   R9   .....   B9   A9
//
//
//   NOTE:  the drawings of this package from Micron are
//          Bottom-View  -  everything here is Top-View
//          and rotated 90 deg CW compared to the drawings
//          in the Micron data sheet.   This rotation is to
//          make it easier to hand enter the 96 pins.
//
//   NOTE:  the ball pitch of this package is  0.80 mm  -  not 1.0 mm.
//
//   As written in this geometry:
//
//      The pin Rows are numbered:  1, 2, 3,  7, 8, 9
//
//      Pin Rowss  4, 5, 6  do not exist.
//
//      The pin Columns are designated:   A, B, C, D, E, F, G, H,
//                                        J, K, L, M, N, P, R, T
//
//
//    The Pin Pad Stacks for this Geometry  come from the file:
//
//       bga_0mm8_stack_definitions.txt
//
//    and are use for all of the 0mm8 pitch BGA parts
//    on the DK Board.
