The HS-6564RH is a radiation hardened 64K bit, synchronous CMOS RAM
module. It consists of 16 HS-6504RH 4K x 1 radiation hardened CMOS RAMs, in
leadless carriers, mounted on a ceramic substrate. The individual RAMs are
fabricated using the Intersil radiation hardened guard ring, self-aligned silicon gate
technology. The HS-6564RH is configured as an extra wide, standard length 40 pin
DIP. The memory appears to the system as an array of 16 4K x 1 static RAMs. The
array is organized as two 8K by 4 blocks of RAM sharing only the address bus. The
data inputs, data outputs, chip enables and write enables are seperate for each
block of RAM. This allows the user to organize the HS-6564RH RAM as either an
8K by 8 or a 16K by 4 array.
This 64K memory provides a unique blend of low power CMOS semiconductor
technology and advanced packaging techniques. The HS-6564RH is intended for
use in radiation environments where a large amount of RAM is needed, and where
power consumption and board space are prime concerns. On-chip latches are
provided for addresses, data input and data output allowing efficient interfacing with
microprocessor systems. The data output can be forced to a high impedance for
use in expanded memory arrays. The guaranteed low voltage data retention
characteristics allow easy implementation of non-volatile readswrite memory by
using very small batteries mounted directly on the memory circuit board.
