1. An integrated circuit memory comprising:
a plurality of storage elements arranged in rows and columns;
a plurality of word lines, each word line connected to a respective row of storage elements and being connected to a respective address decoder;
a plurality of address lines extending from address circuitry to said address decoders, each address decoder being connected to a certain combination of said address lines representing a certain address value to which the address decoder responds to assert its associated word line,
wherein said address decoders are connected to said address lines in a manner such that only one of said address lines is connected to adjacent ones of said address decoders.
2. An integrated circuit memory according to claim 1 wherein said address decoders are connected to said address lines such that the average propagation delay of said address lines is substantially equal.
3. An integrated circuit memory according to claim 1, wherein the address lines are organised in pairs, each pair having a true address line and a complementary address line.
4. An integrated circuit memory according to claim 1, wherein said address lines extend substantially perpendicular to said word lines.
5. An integrated circuit memory according to claim 1, wherein the address decoders are connected such that all address lines except one are alternated between successive decoders.
6. A method of manufacturing an integrated circuit memory comprising: a plurality of storage elements arranged in rows and columns; a plurality of word lines, each word line connected to a respective row of storage elements and being connected to a respective address decoder; and a plurality of address lines extending from address circuitry to said address decoders, the method comprising:
connecting each of said address decoders to a certain combination of address lines representing a certain address value to which that address decoder responds, wherein said connecting step is carried out so as to connect only one of said address lines to adjacent ones of the address decoders.
7. A method according to claim 6, which comprises the step of determining the average propagation delay for the address lines prior to implementing the connecting step.
8. A method of manufacturing an integrated circuit memory according to claim 7, wherein said address decoders are connected whereby the average propagation delay of said address lines is substantially equal.
9. A method of determining the connections between a plurality of address decoders and a plurality of address lines in a memory array, said method comprising:
denoting n pairs of address bits, wherein the nth pair of address bits are the least significant bits of an address word;
defining n operations of said n pairs of address bits, each operation changing the value of the address word when performed on said address word, wherein each Kth operation, where K is an integer between 1 and n, comprises incrementing the Kth pair of address bits by one term of a 2 bit Gray code and inverting the remaining pairs of address bits;
performing said n operations in a predetermined sequence wherein operation (K1) is performed every 4K operations, otherwise operation 1 is performed, where K increments from 1 to (n1), whereby a sequence of address words is generated wherein only a single bit has the same value for adjacent address words in said generated sequence of address words.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.

2. A protective cover for a limb comprising:
a tubular member having a proximal end and a distal end;
a plurality of tubular extensions disposed on the distal end of the tubular member wherein the tubular extensions have a first end and a second end wherein the first end of the tubular extensions is closed and the second end of the tubular extensions is in fluid communication with the tubular member;
a limb opening disposed at the proximal end of the tubular member wherein the limb opening has an inner circumference;
an adhesive strip disposed on the inner circumference of the limb opening; and
a layer of non-adhesive material removably attached to the adhesive strip.
3. The protective cover of claim 2, wherein the protective cover is water-impermeable.
4. The protective cover of claim 2, wherein the protective cover is disposable.
5. The protective cover of claim 2, wherein the protective cover is plastic.
6. The protective cover of claim 2, wherein the tubular extensions are adapted for encasing the fingers and thumb of the hand.
7. The protective cover of claim 2, wherein the tubular extensions are adapted for encasing the toes of the foot.
8. The protective cover of claim 2, wherein the adhesive strip adheres to a subject’s skin.
9. The protective cover of claim 2, wherein the adhesive strip is water-resistant.
