description
The TM16SM64JBN is a 64M-byte, 144-pin SODIMM. The SODIMM is composed of sixteen TMS664814DGE,
8 388 608 x 8-bit SDRAMs, two per board-on-chip/ball-grid-array (BOC/BGA) package mounted on a substrate
with decoupling capacitors. See the TMS664814 data sheet (literature number SMOS695).
operation
The TM16SM64JBN operates as sixteen TMS664814DGE devices that are connected as shown in the
TM16SM64JBN functional block diagram.
