Description
Fairchild Semiconductor Electronics Semiconductor Divi-
sion’s Bipolar Field Programmable Read-Only Memories
include both standard and power-switched versions. CS/PS
inputs provide logic flexibility and ease of memory expan-
sion decoding. SPROM power-switch circuitry is activated
by the PS input.
Fairchild Semiconductor PROMs and SPROMs are manu-
factured with nichrome fuses and low power Schottky tech-
nology. The devices are shipped with all bits in the HIGH
(logical ONE) state. To achieve a LOW state in a given bit
location the nichrome link is fused open by passing a short,
high current pulse through the link. All devices are pro-
grammed using the same programming technique.
Standard PROMs are enabled by a single active LOW CS or
by both active LOW CS and HIGH CS inputs. Power-
switched PROMs (SPROMs) are enabled by a single active
LOW PS or by both active LOW PS and HIGH PS inputs.
See the individual block diagrams for the enable scheme.
